![]() The heart of the RAT's tone comes from a design technique called "Symmetrical Hard Clipping." In this approach, a simple amplifier circuit amplifies the guitar's signal and pushes it across a pair of clipping diodes. ![]() ProCo knew that the world wanted smaller pedals in the wake of brands like BOSS, DOD and Ibanez gaining more and more market share, and they wisely cashed in on the trend. The irony is that it is the same exact circuit as the previous "Big Box" V2 and the following "non-white logo" 1986 V4, as well as the 1988 V5 "LED Version." The "White Face" V3 update was purely cosmetic (some V2s and V3s share the exact same circuit board). The "White Face" model gained a reputation as one of the holy grail RATs, and it even spawned a reissue in the nineties. The V1 and V2 models are the exact same circuit, and simple adjustments to the "Tone/Filter" control can achieve identical sounds from each unit. When switching to the OG mode, you are activating the exact circuitry of a 1979 V1 model, including the accurate "Tone" control rotation and taper. This era of roughly four years covers what is referred to historically as the V1 and V2 models. The OG mode is a perfect recreation of the first production RATs ever made. As you change the mode, the analog circuitry is rewired, resulting in brand new values of resistors, capacitors, diodes and op amps. This is a stepped pot that clicks into place as you scroll through the nine legendary versions of this circuit. This is effectively a simple, low-pass filter. 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. The " Volume" control adjusts the overall volume of the pedal. The operation of the PackRat is about as simple as it gets. 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). 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.īuilding 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. The PackRat is the ultimate tribute to the 40+ years of rodent evolution and its impact on the guitar's sound. Recorders, Classroom & Plastic Instruments.Signal Processors, Converters & Preamps.
