Bluff Chill Devices Ectoverb V1

 Wanna build reverb without a bulky Belton brick? Bluff Chill Ectoverb got you covered. This one is using two PT2399 ICs in series to achieve a quite murky, spacey and lo-fi reverb. Schematic and more info HERE.

Catalinbread Montavillian Echo

 Time to start rolling again...

Here is a discontinued PT2399 based delay from Catalinbread with some filtering I haven't seen anywhere else. Schematic is avaiable HERE.

 

Dunwich DA-120 Overdrive - MOSFET version

 Time for a small break again.

So I think it is time to release beast that I traced with lots of help by evilarsen and built it up a few months ago. It is not a Matamp amp emulator per se, more of a fuzzy overdrive that simulates the sound of a cranked Matamp. It also includes a power amp emulator section and a gyrator boost section at the end of the circuit. Also you can use MAX10044 or ICL7660S for the charge pump if you plan to run it on 9v only which sounds best IMHO.

Ibanez LA Metal LM7

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

Schematic is avaiable HERE.

Guyatone PS-106 Double Octave

 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!

 

 

 

Sobbat DB-2 Drive Breaker

 

 

 

 

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.

 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.
