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.
The operation of the PackRat is about as simple as it gets. The “Volume” control adjusts the overall volume of the pedal. The “Distortion” control lets you raise and lower the amount of gain or distortion that the circuit produces, and the “Filter” control allows you to brighten and darken the sound of the overall effect. This is effectively a simple, low-pass filter. Lastly, we have “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.
