A quite interesting Rat derivate which is also found the "LA" mode in the newly released PackRat pedal from JHS.

Chris Stelloh sent me an old handrawn factory(?) schematic of this old glitchy octave down fuzz (once again, thanks Chris!). It is obviusly inspired by MXR Blue Box but several tweaks and mods had been done such a "Normal" control for clean signal and an octave switch. The original schematic was quite a mess so we had to clean it up in order to do a layout. Chris built it up and he eventually verified it. So here it is...an old forgotten. vintage octave down fuzz!
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.
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.

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.

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