I do not own this one anymore, but here is a photo I took of the guts. As expected, it looks very similar to the Pharaoh (they share PCB).

Unlike Pharaoh:

- No Hi/Lo Switch
- No clipping diode selector switch


More raspy and harsh, more high-end, more like a traditional Muff than the Pharaoh.

I can see the ceramic caps....trad Muffs use them in the tonestack, as well as coupling caps. Typically .1 ufs as coupling. May well account for harsher high end. Always nice in a Muff.

I'm wondering about this one: is anyone using higher gain trannies in spots, a la MPSA13's ?

The .47ufs are plain...it may be ceramics are used here just for the tonestack.

My 1970 Muff uses the same....instead of a .01uf, tho, it sports a .012 as a bass cap there.

Have one on hand to ship to Australia and decided to do a quick reverse.
