R14 100K
R15 470K
R16 100R
R17 18K
R18 33K (6K8 if using mid pot)
R19 33K
R20 390K
R21 100K
R22 10K (original ?Lady has 8K2+2K7 and takes output from the junction between them)
R23 2K7

R25 additional 8K2 connected to tone pot wiper from pad, on reverse of board

C1 10UF
C2 470PF
C3 220NF

C5 470PF
C6 1UF
C7 330NF

Beautiful! what's the switching used on this? i can't see the 3PDT lugs so i guess you're using 2PDT? millennium bypass?

He is indeed. We use it where we can on our own builds as we prefer the DPDT stomps for reliability reasons. Used to be for cost reasons too, but it's actually slightly more expensive to use it these days.

Love this build! Great name, decals and I like that you've modified it! Wrote down your values gonna give it a try sometime. Not too sure what you mean for R25, are you saying its between tone lug 2 (wiper) to tone pad 2 on board?
Thanks!

Could that be Monster Magnet influence on the artwork? That would be very appropriate for a Muff!

Beautiful build! Thanks for posting the components, too. It's one of the few muff variants I'm really interested in.

That's Bongzilla on this one. I've got a Magnet promo on my Ultrastoner. Both are Malleus promo's/artwork though.

Done a box for the cherrybomb when it arrives that's yet another ;)

I like Malleus' promos then! It's properly in that Magnet cosmos, which for a stoner-type pedal is precisely how it should be...
