A Muff ... with blackjack and hookers!

[Fuzzonaut]

You can see the hookers hang out around the 2 blackjack tables below the Muff.



This one has been brewing for awhile. It's based on a PCB that mirrors the famous Kit Rae schematic. I finally settled on the following options/additions:

R5, R6 and R19 are in sockets, R4 is on a trimmer.
C1-C5 and C9-C13 are in sockets. C6 and C7 are in sockets on a 2-way switch.
Both pairs of diodes are in sockets on a 3-way switch (no diodes in the middle position).
Q1 and Q4 are in sockets. Q2 and Q3 are in sockets on a 2-way switch.
There's a MIDS knob.
There's a tone bypass switch.
The FB switch connects the collectors of Q1 and Q3, resulting in some cool oscillation and droning.
There's a LPB-1 BOOST up front.

Without the stuff in sockets:



And filled with whatever seemed to be a good idea to start with: mostly à la Green Russian, but with 6x 220N, 3x 500pf, 1N914/none/LED and 1N914/none/GE for clipping options. Q1 and 4 are 2N5088, Q2 and 3 are 2N5088/KC507.



Boring loop test run with the components mentioned (no input for the osc/drone part):

Now, what else to stick into it?

Very nice! What are your black glass diodes? (Vf)

Thanks. Those are some OA10/CV7049 (Mullard). I got them recently and put them mainly for looks ha-ha, I didn't even measure them.
But now I just did: 275mV.

Awesome build, I love the concept of these multi option pedals, but everyone I've tried I get to the first tone I really like and then it never moves from there, I guess I'm a set and forget fan.

Very cool. I love the art too, it looks like a…big….muff…is that? No….

Love the layout of that PCB.

Yeah, I totally get that and hardly touch any pedals on my boards ... but I really like muffs and just had to build this.

Thanks and uhm ... well ... it's ... yes, but Mary is there too ... so ....

Art is suggestive subjective, gotta love it.

Love LoVe LOVE the 220n in place of 100n.


I remember wanting to get that PCB, but can't remember if I ever pulled the trigger on it — if I did...
I'm gonna build my own Muff, with blackjack, and hookers...
