Wow, looks not really hard to build... :-)

but, what are the boxes called "1" (INV_XX).
I image it's a sort of logic port.

Any idea what could be the chip involved ?

Emma Discumbobulator V2

I just realized that there is a second version of this pedal, and I hope we'll get this traced.
The first version was based on the MXR envelope filter, with some mods, maybe with additional buffer(s). Clones of the MXR that had the mods described on tonepad sounded more or less identical.

I merged all Emma - DiscumBOBulator post into one thread because all the schematics have dissapeared as well as all gutshots.
Please use the attachment function to preserve shit for posterity! thanks

Here are some guts i've found a while ago.
I'm still trying to figure this one out.

Cheers.
