TC Electronics Mojo Mojo Overdrive
Per request. The layout stays mostly true to the schematic. One half of the op amps was unused to I used it for buffered Vref which doesn’t hurt. Quite an interesting design if a bit over engineered.:-)
Biyang Tonefancier BL-8 Blue
This one is kind of a take on a single opamp overdrive with hard clippers ala OD250/Dist+, but the gain control is placed on the feedback loop like in many standard overdrive designs. Nothing too speacial or different, but a nice addition to overdrive palette nevertheless. Snippet from the spiel:The BL-8 delivers a creamy yet … Read more

Grind Custom Fx Spasm Chasm
By looking at the component values, this appears to be a smoother, tighter, civilized and mid oriented Muff variant especially when you compare it to Ultrastoner and TSM680…
Danelectro FAB Distortion
Based on Maxon Distortion Master but with a hardwired bass control and different component values along the signal path. The buffered bypass swithing wasn’t included in the schematic so I left it out.

The internal trimpots is taken out on the outside for external gain controls. And a onboard voltage inverter was added. Schematic: … Read more
