weird, the only thing i can think of is that it is because this was a limited run of them that was supposedly tuned a little different, i think it said that it was closer to the vintage sound. having the board gooped seems like a bad idea, there are so many trim pots that you wouldn't have access to.
is yours a chicago iron blue box one?

The trim pots all have little stickers over the screwdriver adjustment to keep the paint out. Their PCBs have card contacts so they plug them in and calibrate on a test rig before wiring into the pedal so it can still be recalibrated. I seriously doubt there is any difference in the circuits. More likely that DAG asked for a custom color that they could charge an extra $200 for.

totally, i would guess they sound the same too, it wouldn't make any sense to not tune them all the same.

so here are the values of the IC's / Transistors i could make out...sadly a couple were sanded off and painted over it seems.

you can right click and view the image in full, but the only thing that seems to be cut off is the green circled "2N560 - 520"

sure thing, hopefully those numbers check out...they were hard to read, it looks like they are all painted over to make them extra hard to make out.

Sorry for waking this forgotten thread :D but has anyone built one or gotten farther with the schematic?

I know this is an old post, but I have one one of the original Tycobrahe Pedal Flanger pedals in for repair. The one with the MN3001 BBD. Does anyone have a schematic of this pedal that uses the MN3007 BBD? The MN3001 seems to have no output and impossible to locate.

And as a contribution to this Tycobrahe Pedal Flanger thread, I've found that the SN72L044 quad opamps in this pedal can be replaced with a pair of TL022 (8-pin DIP) dual-opamps - placed butt-to-butt. The SN72L044 is impossible to find; and a strange quad-opamp in that it has two independent power supply connections - one for each dual-opamp section. Turns out that two TL022 dual-opamps, (when placed butt-to-butt), match the pinout of the SN72L044 exactly.
