JHS Pedals Packs Nine Elusive Rat Variants Into the PackRat
October 30, 2021 · 5 sources

JHS Pedals announced the PackRat, a compact distortion pedal that puts nine versions of the Pro Co RAT circuit into one box. The newly announced pedal gives a player "9 Rat pedals in one very compact pedal," as Gearnews put it on the announcement1. MusicRadar described it in the same terms: the PackRat "crowds 9 classic and rare RAT distortion circuits into one compact stompbox"2.
The nine circuits are not loose approximations. Guitar World reported that the PackRat "contains nine authentic, rare and vintage versions of the classic rodent-themed distortion pedal," and that the versions are guided by a proprietary digital runway system of 261 components via 40 switches3. In other words, rather than building nine separate analog circuits, JHS Pedals used a digital component network to recreate each Rat variant's behavior, with the player selecting between them.
What the PackRat covers, as reported at launch:
- Nine different Rat circuits in one pedal, spanning classic, rare and vintage versions of the Pro Co RAT13
- A proprietary digital runway system of 261 components, routed through 40 switches, that carries the circuit variations3
- A single compact stompbox format, in place of a board full of individual Rat units2
MusicRadar later characterized the company's motivation in compiling the nine-circuit pedal, noting that JHS Pedals "was so besotted with this gnarly and versatile pedal that it compiled a nine-circuit mega-Rat"4. Gearnews counted the PackRat among the standout pedal releases of 2021, asking readers, "How about 9 Rat pedals in one compact unit?" when rounding up the year's notable effects5.
