Rocktron Big Crush Compressor [Sustainer Compression Guitar Effect Pedal], 2003, made in China

Link: Owner's Manual

The Big Crush Compressor pedal has been specifically engineered for low noise and super long sustain without tone compromise. Unlike other compression pedals that can effect your tone and “fuzzes” as the signal decays, the Big Crush will ring on.

The Big Crush will allow you to hear every note. Great for today’s modern guitarist using 7-String guitars or guitars with super heavy gauge strings - the Big Crush will allow all notes to be heard in their true glory.

The Big Crush is built into a super tough road worthy extruded aluminium chassis. This pedal will stand up to the abuses of time and road wear and tear.

The easy access battery compartment will make chang- ing batteries during a gig a breeze. We have also equipped it with a super bright blue LED so you will know when the pedal is on...
