In 1978, the most versatile and influential distortion pedal of all time was invented in Kalamazoo, MI: the Proco RAT. Scott Burnham and Steve Kiraly first had the idea after playing, repairing and modifying all the available distortion pedals on the market. They wanted a pedal that could go from overdrive to distortion and then all the way to fuzz.
The PackRat is the ultimate tribute to the 40+ years of rodent evolution and its impact on the guitar’s sound. Artists from every genre have used the iconic tones in this unassuming black box to create their sounds, including Nirvana, John Scofield, Pink Floyd, Metallica, REM, the Eagles, Jeff Beck and Radiohead.
Building on JHS' Multi-Mode pedal series that includes the Muffuletta and Bonsai, the PackRat uses the same unique digital runway system to direct the paths of 261 components through 40 individual switches. This means that when you choose one of the nine legendary or rare modes, you are playing fully analog circuits that perfectly replicate that mode, even down to the aging components (also known as component drift).
The operation of the PackRat is about as simple as it gets. Besides the Volume, Distortion and Filter controls, they have included a Mode control. This is a stepped pot that clicks into place as you scroll through the nine legendary versions of this circuit. As you change the mode, the analog circuitry is rewired, resulting in brand new values of resistors, capacitors, diodes and op amps.
