The QuarterMaster QMX is a professional quality, true bypass looper that will help ensure the sonic
purity of your guitar signal by bypassing any unused effects. At the heart of the QuarterMaster
QMX are True Bypass Loops, engaged by stepping on our own custom-designed stainless steel
OptoKick footswitches. High quality gold contact relays are used to maintain excellent signal quality
with extremely low switching noise.

TRUE BYPASS LOOPS:

FLIP/FLOP MODE:

FLIP/FLOP = Push button next to the RTN of each loop
Button OUT
BLUE LED =
Standard Mode
There are lots of different uses for the QMX; it's designed to make life just that little bit easier!
On the left of each loop send / return you'll see a small push button. With the pushbutton left OUT
your QMX will operate as a standard 'in series' Effects Looper. This mode is indicated with a BLUE
LED. Loops will only disengage when the loop's footswitch is pressed a second time.
Pushing the button IN will activate the 'FLIP/FLOP' mode. This is indicated with a RED LED.
This enables you to override other FLIP/FLOP mode selected loops and switch seamlessly between
different pedals such as overdrives, delay pedals etc with a single foot-switch. The other BLUE LED
loops, which are in standard mode, will not be affected. You can also use the RED LED switched
loops as returns for instrument inputs to easily switch between guitars for example.

POWER REQUIREMENTS:

9v DC. Minimum of 50mA per loop required for correct operation. Insufficient mA will result in loss
of function. We recommend using The GigRig Generator for trouble free operation.
Power requirements for each unit are:
•
QMX2: 9v/100mA
•
QMX8: 9v/400mA

The QMX looper does not pass any guitar signal through
unreliable mechanical foot switches.
•
When the status LED is off, the guitar signal is sent through a
true bypass relay direct to the output.
•
When the footswitch is pressed, the Pedal(s) within the Send
(SND) and Return (RTN) loop will be added to the signal path.
•
Features a true bypass loop, with automatic input muting of
the pedal in the loop when in bypass mode.
