Actually I got this pedal several months ago, but I never had the chance to record a demo!!


Basically it’s identical to the current ProCo Rat 2, but JHS added a switch toggle and changed the knobs (these are much better imho)


The toggle switch gives you 3 clipping features:
we give you three clipping gain options (DOWN=vintage Si, MIDDLE=open boost, UP=LED turbo RAT)

  • LEFT: Vintage Silicon. The Vintage mode is really awesome with that unmistakable character.
  • MIDDLE: Open Boost. This mode has a really incredible volume, although the pedal is really quiet!!
  • RIGHT: LED turbo RAT. This mode provides an incredible distortion with a typical aggressive tone

It’s a really good choice and it sounds good on smaller amps and transistor too!


JHS replaced the power plug with a standard 9V DC center-negative plug (Boss type).
It has also the battery clip, but it’s reachable by opening a little door on the back (1 screw).


Here’s the settings I used for the demo (click to zoom)


The JHS Proco Rat is phosphorescent!!


For the demo I used the SM-57 + Scarlett Focusrite 2i2

I was born on 05/02/1989 in the beautiful Taormina, a little town not too far from Messina, Sicily. I live in Bergamo since I was very young; Now I work here as Web Developer. I have various hobbies: informatics, electronics, videogames, cars, magic, cinema e, my passion, music. My approach to music happened very early in my life: I began playing the guitar when I was 4. There also was a keyboard at home, so I could play 2 instruments; this allowed me to learn how to play several instruments later. The guitar remains my favourite instrument, my idol is (of course) David Gilmour. I often sing while I play the piano. I have a good experience with bass and drums.
