Original buffered bypass version

 

 

...and a requested true bypass version.

BJFe Emerald Green Overdrive

 Four resistor value changes and an added resistor transforms an Emerald Green Distortion to an Emerald Green Overdrive....

Cornish P-2

 There was an layout in the library based on an inaccurate schematic. It's been taken down since Aion did a new trace. Schematic is avaiable HERE.

Smallsound / Bigsound F*ck Overdrive

 This one has been on many peoples list for years...

Traced by Deadend Fx and the schematic is avaiable HERE.

A "Sag Depth" pot is the only mod but if you want to build it as the original, just replace the pot with a 1,5k resistor.

Verified by Tom.

Silent but alive...

 My Blogger account comment function is messed up and has been for quite some time. I still can admin the blog as usual but I'm dead quiet... Don't want to give the impression of being snorky or ignorant. I really appreciate all the verifications, visits and comments!😊

Death By Audio Assault System - Op Amp channel

 ...and here is the op amp channel.

Schematic

(might to a complete layout for both channels if there is interest. It will require some extra offboard wiring due to two separate bypass switches and an order switch....) 

 

 

 

 

Death by Audio Assault System - Transistor channel

 An old super rare DBA pedal which was a two channel fuzz. Here is the transistor channel which resmebles most older DBA designs; cascaded reverse beta transistor gain stages. Socketing your transistors is a must since you need to find ones that doesn't gate too much. Also, there is a Filter control which is a variation of twin notch filter. Shape control is a simple ground lift for the filter circuit. 

A big thank you to Nils at Moonn Electronics for the trace!

Grind Custom Fx Tenebrion Reverb

 Based on the Box of Hall circuit but tuned a bit darker and wider range for the Tone and Feedback controls.
