Mutant Bass Drum not working at all

Author Mutant Bass Drum not working at all

I just finished building my Mutant Bass Drum, plug it in and nothing happens. Tried a different power cable and still no go.. I rechecked all my resistors and verified everything is in correct. I also went back over all my solder joints.

I can't seem to find any info on test points where I can check for appropriate voltages when plugged in. Maybe the voltage regulator is bad?

Ive built several other diy modules as well as the 2 other Mutants with no issues. Any advice would be great, Im a bit stumped.

Thanks!

What version PCBs? Didn't have any trouble with mine.

Hey sorry guys, I didn't get back for months on this one. Life got crazy busy and I haven't touched it since I made the post. I about to pick it back up mess around. Did either of you guys get yours up and working?

Same here, only dist side is working.
Any luck?

same problem here with 1.05 pcb ...

the distortion side is working.
trigging is not working at all.
when the trimpot screw of the decay is at max, the module oscillate and the green led is blinking.
when shunting the trig jack with one of the leg of the TL072, the trig is working twice (double trig : rising edge and falling edge ?)

No electronics expert here, but I had the same problem... until I realized I hadn't set the Accent jumper on the PCB.
The module doesn't work without it...could this be your issue?
