Wampler Thirty Something

 Schematic avaiable HERE.

Paul Cochrane Timmy V2

 This one has been requested for some time but since there was no confirmed schematic avaiable I didn't want to pull the trigger. But Aion Fx just uploaded a schematic with their Termina project. It also includes a trimpot which affect the bass response and clipping. Schematic and more info is avaiable HERE. 

Nordland ODR-C

 Schematic and circuit info avaiable HERE.

Schumann F Loop

 Here is a an old, rare and weird one traced by Deadend Fx.

It is a feedback looper that includes both modulation and an active filter sections. If you you don't like the hassle with the offboard wiring this layout requires, Deadend Fx has nifty PCBs for sale.

Schematic and more info HERE.

 

Guyatone PS-024 Distortion H

Guyatone realeased some very interesting, innovative and good sounding circuits in the 80s. Since they are sadly overlooked and quite rare, Deadend Fx decided to trace and release PCBs for some of these gems.

PS024 Distortion H shares some similarities with Boss HM2 but it still differs enough to not qualify as a clone. The most eye catching feature is the 5 band graphic eq at the end of the circuit with its dedicated graphic eq IC which can be found at Ebay and Alliexpress for quite cheap.

 Schematic avaiable HERE,

Crazy Tube Starlight

 Per request. Schematic is avaiable HERE.

 

 

Fuzzlord Effects FET 120 Overdrive - transistor version

 Another one traced by evilarsen. A J FET preamp emulator loosely based on Orange OR120.

This one is already verified. 

 

 

 

 

 

 

Lell X-Metal

An old russian Boss MT-2 derivate. The eq section and the general topology is pretty close to the original. But cap and resistor values differs quite a lot in most places and the gain control looks like it is borrowed from a Boss DS1.  

 

 

 

Keeley Java Boost

 

Keeley Katana Boost V1

 With onboard voltage doubler for more headroom.

Schematic and more in HERE.

Mini EVH

Per request. A DIY project posted by Dylan159 at FSB a while back. It is based on Bajaman's EVH OD but tweaked and simplified. Schematic and more info HERE.

Orange Rockreverb Preamp

 

DOD 210 FET Preamp

 Here we have a small one, an old J FET booster. Polarity protection diode and power filter cap has been added and the 22k Drain resistor is replaced with 50k trimpot so we can socket and try out a wide range of J FETs.
