MIAB pedals

I built a Golden Falk for a friend, but my fav is the PPCB Paradise Overdrive (clone of the Lovepedal Silver Jubilee).
 
CMATmods Brownie is a good one.
I like my BSAIB2, and if I'm not mistaken this pedal is based on it.

If we're just naming MIAB pedals I'll throw the CrunchBox and SL Drive out there (bonus: there's PedalPCB versions to compare to). Of the two, CB is more flexible. I don't find much range in the SL Drive, but what it does it does well. I enjoy both these pedals. JHS has several variations on the CB too, which itself appears to be derived from the Guvnor (which I've heard referred to as the "first MIAB").

I also really like the Dirty Shirley, which is based on a Friedman amp that is based on a Marshall amp.

I like MIAB pedals. I don't have a Marshall, and I've not much experience playing on one though. I'm satisfied with pedals that call themselves MIAB.

Jetter Gold 45/100

This is the single pedal version https://store.jettergear.com/product/gold-45-100/

of this one: https://store.jettergear.com/product/gold-standard/

This is a gutshot, where we can see anything :)

We can just see that both the channels are based on op-amp circuit (as well a pair of two other known Jetter pedals' schematic).
I guess I see two transistors for every circuit.
The side are not totally the same. I think the 45/100 based on is the one without switch channel. From the inside view is the one on the right.

Edit: here's a gutshot of the Jetter 45/100.

I'm building the PAL 800 on stripboard.

(Off topic: I'm stuck in a peculiar issue, I have good voltage for the first two transistors, but voltage changes for the other transistor if I turn the Gain pot, just when the Mid pot is not at min.)
 
Anyway, I'm thinking about that this is op-amp based on, ok. What about the two transistors? Maybe it doesn't enough parts for input and output buffer/boost, maybe the two transistors are for clipping: soft clipping like the Zen Drive, or hard clipping like the OC. Mosfet in both the case, right?
I've seen only one Jetter schematic so far. Gain Stage Red - two mosfets as clippers. Zendrive with a slight mods.
