I traced the Caline English Man pedal,
here the schematic of it.

Oh, I forgot, i made curve traces of the clipping LEDs too.

So it's a single channel c. martin plexitone. :)

Thanks, Manfred.
It looks like the TC1044S doubles the supply voltage, so it's permanently 18V internal? Those can be a source of high pitched whine, if things aren't quite right, of course.
I don't see a volume knob, in the schematic. I assume it's a 100K pot, or maybe a 10k pot, across the output?
It would be nice to see some gut shots. I had assumed all of Caline's analog pedals were through-hole, but I see the Red Devil isn't, from mirosol's picture of it:

I have modified a couple of pedals built with SMD parts, like that, but it's pushing the limit of what I can do, and I'd far rather work on through-hole ones, like the Orange Burst and Pure Sky.

You cannot see it, since in that case it is "LEVEL" called.I don't see a volume knob, in the schematic.

Thanks, Manfred.
Calling it Level wasn't the problem - I just missed seeing it all together. I'm so used to seeing a pot across the output, which is a bit half-assed, but seems to be the most common way of doing it.

I finally managed to get one of these. They used to be all over ebay, but it's hard to find them now.
I wanted to compare this to the Mosky Plexi-m because the Plexi-m had a background fizz to it, noticeable on note decay.
I wasn't sure if the fizz might be a feature of the Plexitone circuit, or just the Plexi-m, or just my pedal.
My English Man does not have that same fizz, and I've now fixed the fizz on my Plexi-m (it was a bad op amp, see here).
Since the Plexi-m has some differences to Manfred's English Man schematic, I thought I'd trace my English Man.
Sometimes I like to double check what I have in MY pedal - these pedals can change over time, with new revisions, and I wouldn't be surprised if sometimes they might populate with whatever components are largely available and "near enough".
And of course, the factory can make mistakes.
I found some differences in my English Man compared to Manfred's older schematic.
Here's what's different on mine:
Additional C2
Additional D6
C4 = 470pF
Gain pot = A1M
C12 orientation
Order of the op amp sections used
Tone pot "direction"
So here's the schematic and some photos for MY English Man, bought in 2021.
