I'm not even a fuzz guy, but the demos I've heard of that thing sound excellent.

It looks like it could be made on a Foxx Tone Machine pcb. The octave and swell could be wired offboard.

This is not that easy . I try many times with Foxx schematic and it never sounded the same as Experience .

What Betty said; I've often thought of trying to build it on a Foxx PCB.
There's just never enough time to do all the things...
@mikiluk1012 , what do you think the crux of the problem is with using the Foxx PCB, based on your experience? (pun intended)

I have both of them (Real Foxx Tone Machine and Real Experience) and there are differences on PCBs and you hear some differences in mid range and amount of gain. Schematics are really similar, but the difference is in the transistors, capacitors and potentiometers. . Of course, to do Experience, you need to add a Swell section that Foxx doesn't have.

Not if you haven't traced it.
Unfortunately, this URL doesn't work anymore:
However I did make a PDF of the pages relevant to the discussion here. PM me if anyone wants the PDF.
Those schematics and block diagram above, well, if their associated website doesn't work I can't direct people to it, then can I?
If somebody gets the shorts in a twist I'll take the trio above down, but until then, there they are, not exclusive to a defunct website.
Something that does still work that I can direct your attention to is Turretboard dot org.
You'll find this trio there:
From the Turretboard.org site, regarding the above:
" Redraw was done from Prescription Electronics Experience unit, and octave on/off stomp switch, and cool swell (fade in) option is added...

This was written on original layout (I’ve downloaded it a long time ago – I don’t remember who made it, so I can’t give a credit – sorry ):
– Foxx Tone Machine: transistors are 2N3565; Diodes are 1N34A
– Prescription Experiance: transistors are 2N3904; Diodes are 1N4001
– This version: transistors are BC549C; D1, D2 are 1N4148, D3, D4 are OA90 – NOTE: BC549C shown, 2N3904 pinout is reversed"
Some other bits 'n' bobs I've collected down this particular rabbit hole:
I thought I had a better version of the vero above, under "prescription" or "swell" or "experience"... so maybe I do, on a HD somewhere.

I'm sorry. I thought that old wish list had been archived. I'm surprised how an effect so interesting and still in use on some pedalboards out there has so little search for construction.

I know Joe from Grey Bench Electronics has traced the circuit and I’ve seen him use some PedalPCB products but I’m not sure if he’s a member here. I wonder if he’d be happy to share the schematic if we reached out to him?
I for one have been on a Doyle Bramhall II kick recently and he is a prolific user of this pedal.
Neste vídeo ele fornece o esquema, mas como não falo inglês, não sei o que ele diz sobre o circuito. Parece-me que há um problema com a parte do Swell.
Tenho outros esquemas e existe alguma divergência na polaridade dos capacitores junto aos transistores.
