The Pigtronix PXREM Keymaster Signal Router and Effects Loop Pedal is a box of delights that opens up new avenues for connecting your equipment together, enabling you to make the most of any set-up whilst keeping control incredibly simple. With a universal analog signal converter built-in, the Keymaster allows your audio equipment to talk directly with instrument level - guitar - pedals and return the signal with balanced impedance with seamless results. Not only that, but you can create series loops or blend signals in parallel, to master your sonic soundscapes for a truly unique playing and recording experience.


The control layout consists out an In Boost knob, an Out Boost knob, and a Crossfade knob. The In and Out Boost controls enable up to 10dB of gain to be introduced to the incoming and outgoing loop signals. Crossfade acts as an output mixer between Loop A and Loop B in parallel mode - in series mode it is deactivated.


As you'd expect, there is an 18V DC power supply input, and the guys at Pigtronix kindly included a power supply with every Keymaster. With regard to inputs there is: a 1/4-inch jack input for balanced or unbalanced signals; and an XLR input for mic/line level signal - this is bypassed when 1/4-inch input is in use. With regard to inputs there is: a 1/4-inch jack output for balanced or unbalanced signals, which can be sent to an amp, mixer, or DI box; an XLR output for mic/line levels - again this is bypassed when 1/4” output is in use.

The two independent Loop channels (A & B) each have individual Send and Return connections, whilst the Expression pedal input allows real-time control over the crossfade between the two loops in parallel mode, allowing you to create some truly mind-boggling effects. The footswitches allow you to activate and deactivate Loop A and Loop B.

Multi-purpose capabilities


The Keymaster is at home on your pedal board, enabling you to create two preset signal chains with your gear. Not only that, but these channels can be mixed together to create lush textures and powerful sonic combinations. Not only that, but solo performers, vocalists, DJs, rappers etc., will all benefit for the exceptional routing capabilities offered by the Keymaster, and the fact that a mixer-ready level can be sent directly to the sound engineer - saving time and hassle.

Re-amping your signal couldn't be easier thanks to this little beauty. Thanks to its ability to convert balanced line level signals from mixers to effects-friendly levels, and then send a return signal to a balanced output or even a 1/4-inch guitar amp output, you can save vast amounts of time and energy, whilst retaining exquisite tonal transparency.

As you can see, the Pigtronix PXREM Keymaster Signal Router and Effects Loop Pedal allows you to control two separate signal chains simultaneously, or blend them together to create some magic. Even if you don't wish to use a plethora of effects, and simply want a reliable signal converter, it is more than happy to oblige. If you have a two amp arrangement, and wish to use the Keymaster to split an incoming signal into a dual-mono output, it can do that too! Quite simply, the only thing holding you back with the Keymaster, is your own imagination.
