I looked at the schematic for the FZ7 and it does have some similarities but I don't think it's close enough to call it a copy or variant

Here's a screenshot of the Pedalpcb schematic for the Ripped Speaker

Here is the signal chain as far as I can see:
Input > lpf > hard limiting diodes > buffer > single transistor "Fuzz" gain stage  > two transistor, biased "Rip" gain stage > tone stack (baxandall?) > Output

...not sure what the other transistor is doing in the power section, or is that part of the bias?
Opamp Buffer (LPF is just RF, diodes are op amp input protection) > 2 x LPB-1 style gain stages (basically a big muff, minus clipping on the 2nd stage) 3rd stage is another LPB-1 style stage with a Maestro FZ-1 style bias control, > Tilt Style EQ > Output.

Transistor in the power section is a buffer for the V.Ref, saving an op amp.
That's a great breakdown. Thanks. Sounds like it's not an outright clone or copy and is something new they did.
They got so lazy cloning they just cloned themselves.
Who the hell is Bucky?

Guessing that Q1 and Q2 are on the other side of the board.
Good point, but I don't see anything on the other side
