Hi all,

not meaning to beat a dead horse here :D but any chance this vero (ShortScaleMike's on page 3) is verified by now?

thanks

Bit of a bump with a little question.
I was wondering if any of you knows about possible changes to the schematic for the two editions that followed Jim Dunlop's MkII.
There's the slightly smaller MkIIS and the Dirty Donny Edition.

Hello lads, I have a question about using a different array in the pickle. See, our forum brother digi2t suggested the use of an MPQ2222 in this post to simulate old fashioned silicon transistors in a early style Big Muff.
Since the MPQ2222 has the same pinout as the MPQ3904 "pickle chip" it got me thinking. In theory, it should be possible to order a mkII pickle clone PCB from one of the DIY shops, load it with the MPQ2222 and replace the other components for the values that are in my favourite early Muff type pedal. (Hohner Tri Dirty Booster)

I'm just thinking out loud here, please do correct me if I'm wrong ! But if I'm right, then I'm wondering about that added coupling cap before the tone control. (C11 in early.memoirs' schematic) Can I jumper this is or it a necessity to prevent the tone pot from crackling ? If the latter, will it affect the sound of the tone control much ?

thank you for reading this and cheers

Aha, finally found someone who love TDB too.

why not breadboard that Cub?

im just thinking and begin to draw something called Muff Development board. With trannies position like mpq ic (love that because the simetry). Gain, clipping and recovery in one board. And pots (with caps and other) in different board, this can be stacked or via wire. With this, we can build ALL muff variant. Right?

The TDB is nothing short of brilliant ! But before I order all sorts of bits and bobs to stuff the breadboard for an array version, I'm hoping to hear from people more knowledgeable than I am whether or not it's worth the effort.
Perhaps somebody has even experimented with a MPQ2222 in their pickle (or a different array type of muff project) and has some interesting experiences to share ?

These are the pickle boards I could find, all for the mkII version. There might be more, there might even be boards for clones of the first incarnation, but I couldn't find them. The one from Fuzzdog might be an interesting base for your Muff Development Board.

Found another DIY mkII pickle PCB! This one's a bit different, as an IC is not an option.
