The Formula No.55 is a completely different circuit


What's different? (Formula 55)
Howard says it follows the Fender circuit "exactly."
Is it still mu-amps?
Or now single jfets?
Or mosfets?

Sounds good.
Seems to have improved low gain sounds..

Sorry for the necro-bump. I mostly lurk and hardly ever (never) post, but I thought this was worth noting: the Formula 5F6 has been traced! I sent mine over to Robert at PedalPCB, who now sells a PCB. As some might have guessed, the layout is identical to the DLS MKIII- and indeed it uses the same PCB with the same S. Bass & S. Lead designations inside.

Carry on!
