Thank you for purchasing the Suhr Alexa Analog Chorus Pedal.
Please take the time to read this manual to get the most out of the pedal.
The more you familiarize yourself with the features of this pedal, the more
you will enjoy its benets and maximize its potential.
Overview
The Suhr Alexa is a two channel, analog stereo chorus with digital control.
Utiilizing bucket brigade technology, classic chorus tones are achieved with
the extra flexibility of new waveforms, tap tempo and expression speed control.
Each channel contains six unique waveforms that allow you to tailor your
modulation to suite your needs. The triangle and sine waveforms are classic waveforms used in a majority of choruses, however there are two new
custom waveforms, the rotary and photo cell waveforms that allow the Alexa to achieve swirling rotary sounds or pulsing vibe-like sounds. With the
final ramp up and ramp down waveforms, rhythmic chorus tones can be
achieved that give a delay-like effect on sustained notes.
Each channel contains an individual Speed, Depth, Delay and Waveform
option. Channel A contains a switch that allows for Vibrato as well. Wether
you want to have a chorus that can switch from slow lush chorus to a fast
rotary chorus with a hit of a botton, or use it like no chorus has been used
before with the ramp waveforms, Alexa can cover a large range of analog
chorus tones and more.

Powering Alexa
DC Input: Alexa powers with a 9Vdc regulated, center-negative power
supply that can supply 100mA or more, such as a BOSS PSA power
supply.

Getting Connected (Stereo)
Input: Plug the cable from your guitar into here, or from the previous
effect’s output.
Output Right: Plug a cable from here to the right amplifier (or another
effect’s input) for the right channel of the chorus.
Output Left: Plug a cable from here to the left amplifier (or another
effect’s input) for the left channel of the chorus.
BUF / TRU-BYP switch: Located on the inside of the pedal are two
slide switches. The right switch determines if the pedal is in buffered or
true bypass mode. Switch to buffer bypass (BUF) for stereo operation.
Restart the pedal by powering it off and back on to finish setting it in
buffer bypass mode.
WARNING: The true bypass feature is dedicated for the left output only. When
using Alexa in stereo, please set the pedal to buffer bypass, which is located

sends a buffered signal through both outputs, and is the mode that should be
used for stereo scenarios. Alexa is shipped in buffer bypass mode.
