Rocktek Super Delay ADR-01

Gut shots of Rocktek's Super Delay.
All the parts are identified but I have no time to draw the schematics at the moment.

Some traces are burned (due to inadequate power supply I guess). Someone fixed that with some jumpers (two orange wires). You may also notice that the black wire for the battery snap is on the hole marked with (+) on the PCB, and the red is on (-). But that's OK, the wires are reversed at the battery snap too, so everything is wired properly.

Two diodes, D1 and D2 have no codes on them. I'm pretty positive that they are 1n4148. They have forward voltage drop 0.65V and there is a schematic for the ROCKTEK Chorus with the same diodes.

Awww man, there's a SUPER Delay? I only got the regular delay 😢

What's striking to me is how completely different the layout of the pedal is (yours even has actual jumper wires on the other side!), when the only diff between the two is the MN3205 (Rocktek Super Delay) vs MN3208 (Rocktek Delay). Here's some hi def photo of mine if you click, then click a photo, and then click 'Zoom."

Maybe the number of the pedals are the order in which they designed them and they got better as they go along. Anyone know which is the last Rocktek pedal number and what pedal that was??
