Features

The HT-1 is the perfect studio and practice amp, packing all the great tone and innovative features of the award-winning HT-5 valve amp into a 1 Watt format. The patented ISF (Infinite Shape Feature) circuit gives you infinite adjustment over the characteristics of the tone control network and takes you from the USA to the UK and anywhere in between. So now you can effectively design your own tone and finally find ‘the sound in your head’.
In making the HT-1 ideally suited to home and studio use, the aim was to develop a valve amp which sounded full and toneful even at the lowest volume level. With this in mind the Blackstar design team designed a brand new valve power amplifier topology. The HT-1 power amplifier is a low powered push-pull design which produces the crunch and break-up characteristics of a traditional 100W output stage but at a much lower volume. This is achieved by the use of an ECC82 dual triode in push-pull configuration producing 1 Watt output, which is rich in valve harmonics and compression.
The HT-1 also has a fully specified speaker emulated output which further enhances the studio credentials and allows any guitarist to get amazing valve tone straight to tape or disk, or through headphones.
Add to this an MP3 / Line Input, along with a 4-16Ω speaker output which allows you to run the amp into an external speaker cabinet of your choice, and you have everything you need for recording or practising.

Front Panel

1. Input
   Plug your guitar in here. Always use a good quality screened guitar lead.

2. Gain
   This control adjusts the amount of overdrive or distortion.
   When the Clean Channel is selected, low settings counter clockwise (CCW), will deliver a clean sound. As the Gain control is increased clockwise (CW) the sound will move from clean into break-up, until at its maximum position, a full crunch tone is arrived at.
   When the Overdrive Channel is selected, the Gain control adjusts the amount of overdrive or distortion. Low settings, counter clockwise, will deliver a clean sound on the edge of break-up. As the Gain control is increased CW the sound will become more overdriven moving through crunch tones until, at its maximum position, a full distorted lead tone is arrived at.

3. Overdrive Select
   Press this switch to select the Overdrive Channel. When the switch is in the Overdrive Channel is selected. When the switch is out the Clean Channel is in operation.

4. Volume
   This controls the volume of the Clean and Overdrive Channels. Turning it clockwise increases the volume.

5. ISF (Infinite Shape Feature)
   The patented ISF control allows you to choose the exact tonal signature you prefer. Fully CCW has a more American characteristic with a tight bottom end and more aggressive middle, and fully CW has a British characteristic which is more ‘woody’ and less aggressive.

6. Reverb (only on HT-1R and HT-1RH)
   The Reverb control sets the overall level of the reverb effect. With the control fully counter clockwise there will be no reverb. Turning the control clockwise will increase the amount of reverb.

7. Speaker Emulated Output & Headphones
   This output emulates the tonal characteristics of a guitar speaker cabinet and provides a natural valve overdrive tone for connection to a recording device or mixing desk, and for use with headphones. To make full use of the stereo reverb, use a stereo jack to two mono jacks splitter lead to feed two channels of the recording device or mixer (see diagram below). The output will also function into a mono guitar type lead. Always use a good quality screened lead.
   Note: when a lead is connected here the combo’s internal speaker is disconnected.

8. MP3 / Line In
   Connect the output of your MP3 or CD player here. Adjust the player’s volume to match that of your guitar to enable you to play along.
   Note: the connection is stereo.

9. Power Indicator Light
   The power indicator will light when the amplifier is switched on.

10. Power
    This switch is used to turn the amplifier on and off.
