Nine RAT circuits in one pedal
The JHS Pedals Packrat is the ultimate tribute to one of the most influential distortion circuits in guitar history. With nine fully independent and authentic RAT circuits built into one compact enclosure, you can explore the complete tonal evolution of the RAT—from the gritty bite of the 1979 OG v1 to the saturated roar of the Turbo RAT and beyond. Each mode is based on extensive research and circuit analysis of vintage units, including rare prototypes and boutique offshoots. If you’re after the raw punch of the early Fringe Logo model, the smooth character of the White Face, or the hard-edged grit of the BRAT, the Packrat lets you switch between eras with the turn of a dial.
All-analogue signal path with digital switching
At the core of the Packrat is JHS’s innovative digital runway system, which controls the switching of real analogue components without affecting the tone. Each of the nine modes routes your signal through unique combinations of resistors, capacitors, diodes, and op-amps—just like the original pedals they replicate. This ensures that every RAT mode remains fully analogue, delivering the authentic feel, saturation, and response that only analogue circuitry can provide. You’re not getting digital modelling or approximations; you're hearing the actual circuit paths rewired in real-time. It's the best of both worlds—modern flexibility with vintage accuracy.
Simple layout, deep tonal range
The Packrat keeps things straightforward with three intuitive controls—Volume, Distortion, and Filter—alongside a rotary Mode selector. Each RAT version responds uniquely to these controls, making the Packrat far more than a one-trick distortion pedal. From tight, cutting gain to warm, dynamic overdrive and fuzzy sustain, the tonal range here is immense. You might want the compressed snarl of the Dirty RAT, the touch-sensitive response of LED clipping in the Turbo mode, or the op-amp rail-clipping aggression of the LA Metal version—the Packrat is designed to react musically to every tweak. It’s easy to find a sweet spot, but also rewarding to explore deeper.
Backed by obsessive research
What sets the Packrat apart is the obsessive level of research and dedication behind its creation. JHS studied over 100 different RAT pedals—including rare early versions and hand-built prototypes—to build the most accurate collection of RAT tones ever assembled. Former ProCo engineers and employees were interviewed, circuit traces were analysed, and inconsistencies in previously accepted RAT timelines were uncovered and corrected. This isn't just a great-sounding pedal; it's a historically informed, sonically faithful recreation of every important RAT that shaped the sound of rock, punk, metal, indie, and everything in between. The Packrat doesn’t just play like a RAT—it is the RAT, in all its forms.
