Ampeg Sub Blaster

 An old request. It is a biggie but I'm sure someone will tackle this anyway *cough, cough...Chris*.;-)

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!
