This is a GREAT sounding mosfet CMOS overdrive/distortion by Gez.

Whew, what a beast.
Sounds killer for dirty but modern metal guitars on a slightly driven or clean amp. I've found that you can best use it as a "clean" boost (quote marks because it's pretty crunchy with the gain at zero). but if maxed out it crushes the signal and creates an almost broken sounding distortion.
I've managed to get anything from broken Swedish Death sounds to stellar modern metal sounds out of it.
I'll try to modify the layout to add a simple tone control and a clean blend to make it suitable for bass and get it shared here.

Hi Till,
Thanks for the review. It's a cool sounding circuit. Adding a tone-stack sounds like a good idea. :) Cheers / Fredrik

I've done it, also added a BMP tone stack, and damn, it's a mini HM-2, such a monster!

Note that if you connect the + leg of 4.7uf to 13rd leg of 4007, it becomes much more a subtle, gentle circuit.

Sorry for the noob question but can someone please tell me where is the board output? I am trying to figure out where to connect one of the power switch connections. Thanks
