Whoof Rapper

The Whoof Rapper is a very popular dual fuzz pedal. One half is a Whoof Fuzz, and the other half is our Grimm Reaper kit, which is based on a Tone Bender. The Reaper also includes an octave up section to make this one scream. Each has its own footswitch making this rather versatile indeed!

The PCB's in use are our standard Muff Multi PCB, and the Grimm Reaper. 

This is an intermediate level build. Theres no specialist knowledge needed although with three footswitches to wire, you need a bit of experience...and patience.

This kit is supplied with a JP1590XX enclosure.  

  • I Wonder What it Compares to

    This kit compares to the Hoof Reaper. 


    There is no endorsement or approval from any manufacturer and this information is for comparison only.

  • Build Guide

  • Whats Included with Each Option

    PCB Only - Just the plain PCB

    PCB & Components - PCB, onboard components and any pots and toggle switches. 

    Full Kit - As above with undrilled enclosure and off board components (foot switch, Jacks, 9v, LED)

    Full Kit & Drilling - Full kit with drilled enclosure.

  • Case Drilling

    Drilling is an optional extra for the Full Kit. There is a small surcharge for this.


    Drilling includes all the holes for a complete pedal.

  • Knobs

    You will need 7 knobs for this kit. I suggest you get medium sized.

  • Fair Warning

    Please be sure to read the build document before you order. The kits are enjoyable but can also be challenging.

    You will have to identify components, calculate resistor codes and be able to solder them into place. 

    All kits require full assembly and any images of completed PCBs are for reference only.
