PedalPCB / Chuck D. Bones CMOS Raincoat

 Schematic and more info is avaiable HERE.




Seppuku Fx/Jordan Fontaine Memory Lapse

 Another contribution by Jordan. Thanks mate!


I was playing with the Seppuku Fx Memory Loss that you had posted and made some adjustments for more versatility. The schematic we all have to work from is so sketchy I thought people might enjoy a thorough series of mods to it.

First off I added a Mix control. It could probably be done better and would love to hear suggestions. 
The C Taper for Stability gives easier adjustment over where the latch up occurs in playing dynamics. 
I set values at the Filter control. The on/off/on gives a clean delay, dirty repeats and very dirty repeats. If you placed a 1u in either C2 or C3 it creates a totally nuts fuzz.
I set components around the feedback and surge control to taste. 
The increased Time pot is for longer delay times, why wouldn't we want longer delay times?!
I 86'd the switch for the LM386/Pins 1 & 8. I'm not going to use it but it wouldn't be hard for someone to wire it in.

The layout is not verified. It is the result of fixing the board I built from my original layout. 
Hopefully no one minds a few diagonal caps.

This on is verified and good to go.




Frost Giant Electronics Little Acid Fuzz

 

 Phew, loys of work lately so not much time for the blog and building lataely. A few people have sent me some new traces and new layouts. These will be uploaded today. First out is Little Acid Fuzz by Frost Giant Electronics.

Another Frost Giant PCB traced by Sergio. Based on the op amp version of the Little Big Muff from the late 70s. The internal Tone trimmer can easily be moved to the outside for a 2-knobber.
