Here are the guts to a cool volume pedal that can simulate a backwards guitar. Sorry about the picture quality my camera refuses to focuswhen i use the zoom.

do you have a macro setting on your camera? that usually helps a lot for gutshots.

I have a Snarling Dog Erogenous Moan Pedal where only the volume pedal side of the unit works. Clicking the switch to use the reverse side does nothing, no change in sound or LED lighting up. The wiring seems to be stock but I have nothing to compare it to, so I'm not sure. Any help on this would be greatly appreciated!

Take good pics of the front and back of the pcb. The guys here are experts at pointing out dodgy solder joints and other faults.

Here are some pics. Is there a way to test the switch firstly?

This is what I have so far. I'm working on the schematic.

I have one and love the enclosure,the pedal developed a click at the end of the run,I gave it a whirl and changed the volume pot side and the click was gone ,the original pots are sealed,the backwards tape effect sucks but I will try changing the pot and see how it goes.

thanks everyone for investigating this thing, I've always wanted to try it but never shell out for.

I might be wrong I have never used this pedal but based on the description, I thought the "click" was an intended feature on the pedal
The Erogenous Moan is a volume/reverse volume pedal, and can be used as a straight volume pedal. Pushing the footpad causes the volume to swell. At the end of the sweep, the volume cuts off completely. Reversing the process, the volume kicks in, and swells again. At the top of the sweep, the volume cuts off with a simulated click of a guitar pick. The effect is haunting.

Yeah. Here's what I have. Didn't have time to validate it to the board trace tho, so you might want to check it yourself.

Thanks for the schematic. It definitely helped for wiring up the switch. However I still have the same issue of the volume side working but the reverse doesn't work. Which IC controls the reverse of the pedal?
