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!

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.

Emanating Fist LR-01 Lucifer Rising

 

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.

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.

Boss OD-1 - Dual Op Amp version

 Forgot I had the later and more common version in a folder...

For the earlier quad op amp version there is a layout HERE.

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.

TC Electronics Mojo Mojo Overdrive

 Per request.

The layout stays mostly true to the schematic. One half of the op amps was unused to I used it for buffered Vref which doesn't hurt. Quite an interesting design if a bit over engineered.:-)

Boss SD-2 Crunch Channel

 Per request.

Schematic is avaiable HERE and a verified layout for the Lead Channel is avaiable HERE.

Grind Custom Fx Spasm Chasm

 By looking at the component values, this appears to be a smoother, tighter, civilized and mid oriented Muff variant especially when you compare it to Ultrastoner and TSM680...

Danelectro D2 FAB Overdrive

 Schematic is avaiable HERE.

Danelectro FAB Distortion

 Based on Maxon Distortion Master but with a hardwired bass control and different component values along the signal path. The buffered bypass swithing wasn't included in the schematic so I left it out.

 

 

Ltava Fuzz Wah - modified

 The fuzz and wah section of Ltava Fuzz/Vibrato/Wah multi effects pedal manufactured in Ukraine in the early 80s. The LFO section was left out simply because the layout would be too big. The internal trimpots is taken out on the outside for external gain controls. And a onboard voltage inverter was added.

Exar MM-04 Moon Metal

 Based on Marshall Shredmaster but lots of tweaked values and a few addons along the signal path. So it might have its own thing soundwise...
