[sdiy] Roland PB-300 kick: is it an 808?

[Benjamin Tremblay]

It lacks any knobs, but the transistor-controlled pitch sweep, trigger circuitry, and positive feedback decay look similar to me. Am I reading this right?
I’m looking to add some knobs to mine.
The cymbals etc remind me of the CR-5000 but the kick looks like is just needs a little love.
Huh I will try to dig up the schematic.
