QuarterMaster/QMX Instructions
Congratulations on your purchase of TheGigRig QuarterMaster.
This simple yet very high quality true bypass looper will ensure the purity of your guitar's
signal by bypassing any unused effects. In line with all GigRig products the QuarterMaster
looper does not put any guitar signal through foot switches. True bypass high quality gold
contact relays are used to maintain high signal quality sound and extremely low switching
noise.
At the heart of the QuarterMaster are the True Bypass loops activated by stepping on the
footswitch.
Example: With a Pedal connected between the Snd and Rtn, the foot switch will bring the
pedal into the signal path. When the light is off the pedal will be true bypassed.
Power Requirements: Each loop requires 35mA to operate at its best. *PLEASE NOTE* if the
unit is under powered, it will not work properly. We recommend using TheGigRig Modular
Power Supply for trouble free operation. Requirements for each unit are;


you engage the footswitch your signal will be sent to the input of the tuner, and the short
circuit jack plug will silence the signal to the amp.

True Bypass Loop

When the light is off the guitar signal is sent through a true
bypass relay to the output. When the footswitch is pressed
the Pedal or Pedals within the Snd and Rnd loop will be
added to the signal path.

input of your tuner and the jack
