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, footswitchable boost, and a silent tuning mode for maximum flexibility. iv Boost Mode 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 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. 1 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 rolloff 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 counterclockwise 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 reamping. 2 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. 3 Controls at a G tuner: Connect your tuner or use as a second output for a stereo setup, DI for recording, or key signal for a noise gate or sidechain compressor. pedalboard Glance - Buffer guitar in: Plug your guitar in here. The high impedance input won't load down your pickups, so the full frequency range of your guitar can pass through. amp out: This buffered output can drive a long cable run without signal loss. Controls at a G input: Boost or pad the signal from the guitar in jack by 3dB, or set to 0dB for unity gain. tuner: Connect your tuner or use as a second output for a stereo setup, DI for recording, or key signal for a noise gate or sidechain compressor. pedalboard boost footswitch: Press to activate/deactivate the boost. Hold to mute the amp out jack for silent tuning. Glance - Buffer+ noise filter: Select the amount of filtering applied to pedals in the loop. boost: Control how much gain is added (up to 30dB) when the boost is activated by the footswitch. input loading: Control how much load is placed on your pickups. Turn counterclockwise to roll off high frequencies. guitar in: Plug your guitar in here. The high impedance input won't load down your pickups, so the full frequency range of your guitar can pass through. amp out: This buffered output can drive a long cable run without signal loss. 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.
