Catalinbread Karma Suture Silicon

...and silicon version.

Catalinbread Karma Suture Germanium

 Taking a break from the break since this one was too interesting to pass on and it was a quick layout.

Tracing post, schematic and info at Aion Fx.

Lastgasp Art Laboratories Tone Mosaique

 900 post. Phew. I think it is time for a couple of weeks break do deal with "outside world" issues.:-o. Will still log in here now and then and eventually upload something if something really interesting shows up.

But here is a cool design from Lastgasp Art traced by Deadend FX, a bitcrucher/tremolo,/ringmod/envelope follower...thing.  Schematic is avaiable HERE.

Dunwich Amplification Cthulhu Fuzz - 1 knob silicon version

 Time for some doom. Recently traced by evilarsen and an odd fella who likes fuzz. Layout is verified.

 

 

 

 

Seppuku Fx Sub Octave Synth

 Schematic is avaiable  HERE.

Modern SLO 100

 Russian pre amp emulator of a Soldano SLO. D1 and D2 is optional since they only add some compression to the overall sound.

 

 

 

 

 

Lastgap Art Laboratories Misty Cave

 A biggie but it will fit a BB enclosure without battery. If you think this is to big for vero, Deadend Fx have excellent PCBs for this circuit and many other cool designs.

Schematic is avaiable HERE.

Park Auto Wah

 Not an auto wah in a normal sense, more like an inductorless wah circuit driven by an LFO.

This must be one of the earliest modulation pedals and IMO it is a hidden gem. Lots of murky psychedelic madness can be found in this circuit, especially with a dirt box upfront. 

Rate and Depth controls is self explanatory but the Tone control really widens the ranges of tones. Clockwise you'll get normal wah wah sweeps, roll it back and you can dial in vowel and yuo-yuo sweeps. 

With the Depth control CCW, the LFO is disengaged and the unit acts as a eq / filter circuit.

Layout has some mods; power supply mod since original units was positive ground, CBE pinout for the transistors, power filer cap and protection diiode. As for the transistors, most low gain NPN silicons should work, I ended up with PN2222s in the 150Hfe ballpark. 

This is soon to be boxed but need to figure out how to add a rate LED first...

*Edit* Rate LED added with help from Radu.  Thanks!

Greer Southland Overdrive

 

Rochambeau

 This was a request.Based on Fuzzrucious Ram the Manparts but with a bit less gain on tap, no starve control but with tone and clipping controls. Schematic and info HERE.

 

 

 

Laney Black Country Customs TI Boost

 Schematic is avaiable HERE.

Through hole MC33178 op amps seem to have gone obsolete so you may want to try other low noise dual op op amps with BJT iputs such as 4580, NE5532, L833 etc. Or simply TL072s...

 

Screaming Eagle - ENGL e530 Amp Emulator

 Another ENGL 530 amp emulator based on a russian schematic but with quite a few extra knobs and switches added by JOK3RX at FSB.

 Modified for 3PDT bypass switching.
