Introduction
“I am beyond excited to personally invite you into the realm of sonic
brilliance and artistic expression that this amp embodies. My journey with
Blackstar began when I stumbled upon their team at the NAMM show back in 2019.
At that time, I was a 14-year-old kid, utterly mesmerized by the overwhelming
array of amps and guitars surrounding me. It was like being a child in a candy
store, except the treats were instruments that held the power to shape my
musical journey. As I immersed myself in the diverse range of Blackstar
products, I was able to discover my own sonic identity—the tone that resonated
with my soul. Blackstar became more than just an amplifier company to me; they
became the guiding force behind my artistic journey.
From day one, the Blackstar team showered me with an outpouring of kindness
and support. Their belief in my potential as a young artist filled me with
gratitude and determination. They made me feel like a part of their musical
family. Together, we embarked on a quest to find my sound—an odyssey that
initially led me to the HT-20R MkII amp. Blackstar then went above and beyond
by customizing this amplifier to match my personality and style. They covered
it in a vibrant combination of red and cream, creating a visual masterpiece
that spoke to my heart. It was a true testament to their dedication and
commitment to helping me realize my artistic vision.
Today, I am humbled and honoured to reveal the pinnacle of our
collaboration—the St James Toby Lee Signature Amp. This remarkable creation
holds a special place in my heart, bearing my name as a symbol of our shared
musical journey. Its design encapsulates my love for the ‘60s, reminiscent of
classic cars and vintage guitars that hold a piece of history within them.
I carefully chose 6L6 valves for their ability to produce the captivating,
distorted tones that define my playing style. When you unleash the St. James
Toby Lee, you’ll be greeted with stunning tone straight out of the box. The
reverb capabilities across all volumes and channels are nothing short of
outstanding—an essential ingredient for my love of ambient soundscapes. This
amp is a true chameleon, allowing you to traverse genres effortlessly, from
the timeless melodies of Buddy Holly to the thunderous power of Metallica,
this amp can cover it all.
I love the vintage red vinyl and cream basket weave finish, crowned with
luscious cream chicken head knobs. I love everything about the amp so much but
the best feature is remarkable featherweight design, how they’ve achieved this
without sacrificing any tone is beyond me!
Throughout my journey, Blackstar has been an unwavering pillar of support
during my professional development. I started as a young performer, eagerly
leaping onto the stage to join my musical heroes—legends like Joe Bonamassa,
Buddy Guy, and Slash. Now, as an adult with my own band, Blackstar continues
to stand by my side.”
Features
The St. James heads and combos are highly versatile amplifiers suited to a
wide range of playing styles and situations.
Channel I: The valve gain structure and voicing of this channel has been
inspired by classic American amplifiers of the mid ’60s. It is very clean and
bright, but with a solid low-end and controlled mids. Also, on this channel
the valve power stage is set to be tight, relatively clean and linear across
the frequency range.
This is one of the most popular choices for a ‘pedal platform’ as it provides
a solid clean foundation to apply effects to.
Channel II: The ‘6L6’ models use a ‘modern’ preamp gain structure for Channel
II.
This specific channel is a combination of Blackstar’s award-winning cascaded
valve overdrive circuits and a traditional ‘British style passive tone stack’
(EQ). When CH. II is selected but Voice is off, the valve power amp is set to
be tight and relatively linear.
Switching to the alternative Voice setting on these models revoices the
overdriven cascaded valve preamp for more saturation, as well as reconfiguring
the power amp to be open loop, to provide that contemporary high-gain looser
feel with plenty of resonant low end ‘chug’.
All models feature a 3 way ‘Power’ switch to give the user options on how
their valve output stage is run.
On the rear panel, in addition to the expected effects loop and footswitch
sockets, we have also included separate stereo headphone, balanced XLR and USB
outputs.
Key to the great sound from these is two very important additions. First is
the inclusion of an internal reactive load, specially designed to load the
valve output stage in the same way as a guitar speaker. The other is our newly
developed CAB RIG DSP technology to provide the user cutting-edge cabinet,
speaker and room simulation. This opening overview cannot do it justice,
therefore CAB RIG will have documentation all of its own!
Front Panel
-
Input
Plug your guitar in here. Always use a good quality screened guitar lead.
With no jack applied to the Input the amplifier will automatically be switched to a safe, low power consumption, silent mode. -
Volume I
This controls the volume of Channel I. Turning it clockwise increases the volume.
At extreme clockwise settings the preamplifier will start to overdrive slightly. It has a natural, variable ‘bright’ response designed in. At lower settings the tone is ‘brighter’ with comparatively more high frequencies passed though. As the control is increased the perceived brightness is effectively reduced due to the increase in all other frequencies. -
CH. II Select
This switch selects between the two preamp channels, as well as adjusting the response of the valve power amp. With the LED off it is set to Channel I which is the cleaner, ‘mid ’60s American’ preamp and a tight, linear response from the power amp. Switching to CH. II will turn the LED on and activate Channel II.
Channel II on ‘EL34’ models use an early ’60s British style valve preamp gain structure and sets the power amp to be loose and resonant.
Channel II on the ‘6L6’ models use a ‘modern’ cascaded valve preamp gain structure.
The power amp response is dependent on the Voice setting (see below).
When the footswitch is connected this switch is bypassed but the LED will still indicate the channel status. -
Gain II
This controls the gain of Channel II and the amount of overdrive or distortion. Lower settings will clean up and respond well to the player’s dynamics and guitar volume setting. Higher Gain II settings will push the valves harder into progressively more verdrive and distortion. -
Voice Switch
This switch selects between the two voices of Channel II.
On ‘6L6’ models this increases the gain into the valve overdrive section pushing the saturation available from the Gain II control even further. This is great for fluid ‘legato’ lines and sweep-picking techniques, as well as aggressive alternate picking.
On these models the power stage is tight with Voice off and reconfigures to a more resonant response with Voice on, to provide the low end ‘chug’ of modern high gain amps.
When the footswitch is connected this switch is bypassed, but the LED will still indicate the Voice status. -
Volume II
This control adjusts the overall volume of Channel II. Turning it clockwise increases the volume. This is useful for setting the required balance between the two channels. -
Bass
This adjusts the amount of low-end frequencies in your tone. High settings will be fat, warm and resonant. Low settings will be thinner, but sometimes less muddy. This is a dual ‘potentiometer’ with each part working separately and differently on each channel. More on this below. -
Middle
This adjusts the amount of mid frequencies in your tone. The middle frequencies are particularly important in setting the amount of ‘body’ your tone has. As with the Bass control, this is a dual ‘potentiometer’ with each part working separately and differently on each channel. More on this below. -
Treble
This adjusts the amount of high frequencies in your tone. At low settings the sound will be warm and darker in character. As it is increased the sound will become brighter, eventually to the point of being aggressive and cutting. Again, this is a dual ‘potentiometer’ with each part working separately and differently on each channel. More on this below.
Differences in EQ ‘tone stacks’ on each channel and each model:
At Blackstar we are always trying to get the best versions of a specific tone and spend hours (days!) analysing circuits; both electronically and sonically. We felt that despite having one set of EQ controls, a ‘one size fits all’ approach for all the channels was not good enough. Therefore, we have used dual pots for each of the Bass, Middle and Treble controls and kept the rest of the EQ components electrically independent. This means we did not need to compromise on the control frequencies and level ranges of any of them. Instead, we have tuned the EQ to be different for each channel type and have used what is most appropriate for the specific channel.
Channel I uses the same EQ topology as expected for a mid ’60s American clean tone. Bright treble, restrained middle and solid bass.
The Channel II tone stack is configured similar to a British style lead amp for authentic rock tones and the response will be familiar for that application. -
Reverb
The REVERB control sets the overall level of the reverb effect. With the control at minimum there will be no reverb. Turning it clockwise will increase the amount of reverb. -
Power Switch
This 3-way miniature toggle switch allows the user to switch between three very different power output settings:
50W – This is the full power setting which will give the loudest clean headroom. This is likely to be used for live, stage use.
SAG – This includes a power supply ‘sag’ which is a form of dynamic compression that will be most noticeable on loud transients (attack). The overall headroom will be lower than the 50W setting and the ‘feel’ will be softer and more ‘vintage’. Needs to be experienced to understand.
2W – This is the low power setting and as suggested reduces the output power way down to a maximum of 2 watts. This is likely to be used when practising, recording and at smaller gigs, or when a more overdriven power amp tone is desired. -
Master
This controls the overall volume of the amplifier through all the following outputs:
• SPEAKER OUTPUTS (also dependent on the Power switch setting (11).
• D.I. OUTPUT XLR
• LINE OUT / PHONES jack
• USB AUDIO output
Minimum will be no signal, fully clockwise will be the loudest. (You knew that, right?) -
STBY Switch
This large toggle Standby switch selects between two different modes: Position ‘0’ disconnects the main Speaker Outputs therefore there will be no sound from any connected speaker. It also re-routes the output of the valve power amp signal to the internal reactive load. This is intended for silent recording use from any of the CAB RIG speaker simulated outputs. The guitar signal will still be passing through the whole amp from Input to after the power amp, through the internal reactive load and CAB RIG. Therefore, the tone remains intact. As the Speaker Outputs themselves are disconnected in this mode then the unit can be used without being connected to an external speaker load without worry of damage. In certain settings there may be a faintly audible amount of ‘bleed-through’ of signal to the speaker(s). If this needs to be eliminated completely then it is okay to disconnect the speaker lead from the rear panel. (Refer to Rear Panel section 4 for more information.)
Position ‘I’ will connect the Speaker Outputs, therefore driving the speakers as normal, and disconnecting the internal reactive load. The signal sent to the CAB RIG DSP will be from the same point, only now it will be loaded by the external speaker rather than the internal reactive load.
All the CAB RIG Outputs can be used in either position as required or preferred.. -
Power Switch
This large toggle switch is used to turn the whole amplifier on and off.
Position ‘0’ is completely off, the same as detaching the mains cable.
Position ‘I’ is on. Actual functionality will be dependent on other settings, including STBY and the small Power toggle switch, as well as what is connected to Input and Speaker Outputs.
When switched on, the front ‘BLACKSTAR’ logo will light up and inform the band and audience members of your impeccable taste in choosing this product.
Rear Panel
-
Mains Fuse
The value of the mains fuse is specified on the rear panel. Never use a fuse of the incorrect value or attempt to bypass it. -
Mains Input
The supplied detachable mains lead is connected here.
Unusually for valve amplifiers, the St. James products are designed with a universal input power supply. This means that the mains input range is rated at 100Vac to 240Vac and capable of operating at 50Hz and 60Hz. (We actually test them beyond these rated limits.)
Therefore, these products can be used anywhere in the world without needing to adjust anything. Not only will they simply function wherever used, but they will also be completely consistent in tone and output power, regardless of any changes or fluctuations in local mains supply. Along with the size and weight benefits, this makes them ideal for a musician who travels internationally. -
H.T. Fuse
The value of the H.T. fuse is specified on the rear panel. Never use a fuse of the incorrect value or attempt to bypass it. -
Speaker Outputs
The output marked ‘1 x 16 OHM’ is for the connection of a single 16 Ohm extension speaker cabinet or the internal speaker(s).
The outputs marked ‘1 x 8 OHM OR 2 x 16 OHM’ are for the connection of either a single 8 Ohm extension cabinet or two 16 Ohm cabinets.
| ‘1×16 Ohm’ output| 1×8 Ohm or 2×16| Ohm’ outputs
---|---|---|---
Internal 16 Ohm combo speaker(s)| | |
Internal 16 Ohm combo speaker(s)
plus one 16 Ohm extension cab| | |
One 16 Ohm extension cabinet| | |
Two 16 Ohm extension cabinets| | |
Single 8 Ohm extension cabinet| | |
WARNING: The output marked ‘1×16 Ohm’ should never be used at the same
time as any of the outputs marked ‘1×8 Ohm or 2×16 Ohm’. Failure to correctly
match the impedance of the amplifier and speakers will damage the amplifier.
NOTE: Unlike many other valve amps, these have clever sensing and
switching which means that they can be used without being connected to a
speaker load.
If the speaker lead is disconnected at the amplifier end then it will
automatically switch it to a safe, low power consumption mode.
When using the STBY 0 mode then the output is automatically switched to the
internal reactive load, meaning the speaker connection is disconnected anyway.
Therefore, for example, if you wish to record using the head and take the
output from either the XLR, stereo jack, or USB, then you can set it on your
desk without any need to be connected to a speaker load.
IMPORTANT NOTE: The protection sensing is at the speaker output jacks on
the unit. So, do not disconnect at the speaker end only. Disconnect at the
amp!

CAB RIG SPEAKER SIMULATED OUTPUT – MONO BALANCED XLR D.I. OUTPUT socket
This output is for using an industry standard 3 pin XLR cable for connection to a recording device, stage box or mixing desk. This provides a low noise, low impedance, quality connection for recording or live use.
The signal will be the actual speaker output signal (including power valves and output transformer), that has then been passed through the CAB RIG technology, to apply the authentic feel and response of a ‘mic’d up guitar speaker cabinet in a room’. The actual sound is dependent on the CAB RIG switch setting and the more in-depth settings within the CAB RIG software.
More on this in the separate CAB RIG documentation.
As it is derived from post-power amp then the Master control will affect the signal level sent from this socket. -
CAB RIG SPEAKER SIMULATED OUTPUT – STEREO JACK LINE OUT/PHONES socket
This ¼” TRS jack socket provides a stereo connection to connect to a recording device or mixing desk. Always use a good quality TRS (stereo) type lead or TRS to 2 x TS (mono) (see diagram below).
It can also connect to headphones therefore allowing silent practice with the STBY switch set to ‘0’.
Again, the signal will be derived from the actual speaker output via the CAB RIG technology, providing a high-quality authentic ‘mic’d cab’ response. The actual sound is dependent on the CAB RIG switch setting and the more in- depth settings within the CAB RIG software app.
More on this in the separate CAB RIG documentation.
The signal level from this output will also be controlled by the MASTER control.
When using headphones, please take into consideration that loud sounds over extended periods can result in hearing damage, both short term, long term and permanent. We spend a long time making our amps sound good, so we’d prefer that you have a long life of good hearing to be able to enjoy them.
-
CAB RIG Switch
This allows the user to switch between the three currently stored CAB RIG settings. Almost unlimited further options and permutations are controlled and set in the Cab Rig software.
More on this in the separate CAB RIG documentation. -
Effects Loop Return Socket
Connect the (mono) output of an external effects unit here. -
Effects Loop Send Socket
Connect the (mono) input of an external effects unit here. -
Effects Loop Level Switch
The Level switch sets the effects loop to either +4dBu or -10dBV, which enables the user to use it with either professional audio equipment (+4dBu) or with guitar level effects such as effects pedals (-10dBV). If unsure, use -10dBV to start with. -
Footswitch
The supplied 2-way footswitch can be connected here. The footswitch will enable the selection between Channel I and Channel II and also select between the two Voice settings of Channel II.
Note: Using this socket will disable the front panel Channel and Voice Switches.
Therefore, full control via the footswitch is granted irrespective of how the amplifier is set. When using the supplied footswitch, the Channel and Voice LEDs on the amplifier will always display the current setting. On the footswitch, if VOICE is selected for CH. II then this LED will remain lit even when on CH. I, to let the user know the CH. II settings before they go to it. This prevents any surprise of difference in gain or volume when switching channels.
EXTERNAL SWITCHING: This socket can also be used by people who wish to control the channel and Voice switching using an external switching device that connects via a common TRS jack to jack connection.
The following external conditions will switch the Channels and Voices as follows:TIP| RING| CHANNEL| VOICE
---|---|---|---
Closed| Closed| Channel I| N/A
Closed| Open| Channel I| N/A
Open| Closed| Channel II| OFF
Open| Open| Channel II| ON -
USB Audio socket
This B-type USB socket is for the connection to a computer via a suitable lead (not supplied).
This is for USB digital audio output and for connecting to the CAB RIG software.
Again, the signal for the digital audio will be derived from the actual speaker output via the CAB RIG technology; providing a high-quality authentic mic’d cab response. The actual sound is dependent on the CAB RIG switch setting and the more in-depth settings within the CAB RIG software.
More on this in the separate CAB RIG documentation.
For USB audio, standard audio drivers are used to connect the amplifier to a PC, Mac or other applicable recording device. No specific drivers are required.
For a guide on low latency USB recording visit: www.blackstaramps.com/usbrecording
NOTE: Always connect the amplifier via a main USB port; often found on the rear of the computer or side of the laptop. The amplifier will appear as an audio capture device within recording software.
