Safety
-
DANGER! Danger for children
Dispose of plastic bags and packaging properly to keep them out of reach of babies and young children to prevent choking hazards. Ensure children don’t detach small parts like knobs to avoid choking. Never leave children unattended with electrical devices. -
DANGER! Electrical shock
Risk of electrical shock from exposed wires or damaged components. Inspect pedals for damage before use. If damaged, stop use and seek professional repair. -
DANGER! Power Supply Issues
Use the right voltage and current for your pedal’s power supply to prevent damage and safety risks. Check the power supply’s condition, and for multiple pedals, opt for a dedicated supply to avoid overloading by daisy-chaining. -
CAUTION! Overheating
Avoid overheating. Do not stack pedals or place in confined spaces. If a pedal overheats, stop using and let it cool. -
CAUTION! Tripping Hazard / Pedal Placement
Prevent tripping: Secure cables and place pedals firmly to avoid slips and falls. -
CAUTION! Volume Spikes
Beware of volume spikes and unexpected sounds when adjusting pedal settings -
NOTICE! Allergies or Sensitivities
Allergy Alert: Some pedal materials, like adhesives and coatings, may cause reactions. Stop use and seek medical advice if needed. -
NOTICE! Fire Hazard
Keep away from direct heat and open flames.
Introduction
The Empress Buffer and Buffer+ were designed to protect the fidelity of your guitar signal and provide a complete I/O interface for your pedalboard. A high-impedance guitar signal can lose power and brightness over long cable runs. Our buffers eliminate this signal loss and preserve your tone. These pedals also consolidate the connectivity of your pedalboard, making setup quick and easy. The Buffer+ adds an input gain switch, variable input loading, noise filtering, foot-switchable boost, and a silent tuning mode for maximum flexibility.
Boost Mode
The Buffer+ is designed to provide up to 30dB of clean boost for enhancing
guitar tones during live performances and studio recordings.
- Set the desired boost level using the boost knob on the pedal.
- Press the footswitch to activate the boost mode. The blue LED will indicate that the boost is active.
- To deactivate the boost mode, press the footswitch again.
The Buffer+ can provide up to 30dB of clean boost. Set the desired level with the boost knob, and press the footswitch to activate. A blue LED will indicate that the boost is active. Press the footswitch again to deactivate.
Silent Tuning Mode
To enable silent tuning mode:
- Press and hold the footswitch for 1 second to mute the amp out jack.
- A red LED will indicate that you are in silent tuning mode.
- To exit silent tuning mode and return to the previous boost state, press the footswitch again.
Press and hold the footswitch for 1 second to mute the amp out jack. A red LED will indicate that you are in silent tuning mode. Press the footswitch again to unmute the amp output and return to whichever boost state (on or off) the pedal was in before activating silent tuning.
Noise Filter
Set the toggle switch to little or lots to help reduce noise from pedals that
are connected inside the loop, especially white noise or hiss generated by
digital pedals. When using high-gain pedals such as distortion in the loop,
you might notice a change in high-frequency response. This is normal and can
usually be corrected with some gentle EQ.
Input
This toggle switch lets you boost or pad the signal at the guitar in jack by
3dB. This can be useful for matching levels from different instruments, or for
sending a hotter signal to your pedalboard for a better signal-to-noise radio.
Set the switch to 0dB for unity gain.
Input Loading
The main goal of a buffer is to prevent signal loss, but some high-frequency
roll off from a long cable run may sound pleasing. When this side-mounted knob
is fully clockwise, the full frequency range of your guitar signal passes
through. Turn the knob counter clockwise to start loading down your guitar,
changing the response of your pickups, and rolling off just the right amount
of high frequencies.
Alternate Use
The Buffer and Buffer+ can also act as 1-in/3-out splitters. The input signal
is normally routed to the loop out and tuner out. When nothing is connected to
the loop in jack, the input signal will also be routed to the amp out jack.
This could be used to run multiple amps, or to record a separate dry signal
when tracking to use for re-amping. Please note that the grounds of each
output are not isolated, so connecting to multiple destinations could cause a
ground loop. Lifting the audio ground (not the power ground) on one of the
connected devices should solve ground loop issues.

Powering
the Buffer & Buffer+
Go to www.empresseffects.com/power for
list of power supplies we’ve tested.
Please note: The Buffer and Buffer+ require at least 80mA and 86mA of current to function properly, respectively. Any power supply rated at 9V DC supplying negative polarity and at least the minimum required current should work.
