Thorpy Fx The Warthog.

 The last layout of 2022!

Thorpy Fx take on a Rat. An input MOSFET gain stage with a bias control, a fancy high end single op amp and LED hard clippers. Looks fun!

Schematic is avaiable HERE.

Hawk II Tonal Expander

 With some modern improvements:

  • Onboard voltage doubler for 18v operation.
  • Series inductor for the Bass control since stock value is impossible to source nowadays.
  • Master volume control.

Exar SF-02 Super Fuzz

 Another Exar box traced by Vitali from Drunk Beaver pedals. I've been curious about this one for a while. It turns out that the fuzz section are a Boss DS-1 derivate. The interesting part lies in the Eq section. The Frequency pot controls both a Big Muff tonestack (with a very deep mid scoop notch) and an active bandpass filter. The Equilize control pans between both filters...

It came out quite big but it will fit in 125b box if mounted sideways.

Boss OD-3 Overdrive

 Schematic is avaiable HERE.




Jersey Girl Fulltender Overdrive

 A pretty rare japanese boutique OD based on the 77-80 era Boss OD-1. The LF444 are a quad op amp with J FET inputs so TL064/TL074 are suitable replacements.

DNA Analogic Gain Fxxker V2

 Schematic is avaiable HERE.



DNA Analogic Smoky Fuzz

 This is pretty much a souped up DOD250/MXR Distortion Plus derivate with more gain on tap and useful gain control. But the most interesting thing is the "Sens" control which pand between a low pass filter and hard clipping diodes.

Schematic is avaiable HERE.
