Pro-10 Dual with Relay Bypass

[Joben Magooch]

Hi all,

Just a (hopefully) quick two-part question.

I've built the Pro-10 Dual OD ages ago. Today I was wondering: Would it be possible to retrofit it with relay bypass (soft-touch switches)?

1. Will they fit?
Quick back-of-the-napkin math seems like there is enough width for two relay PCBs side-by-side, but I'm more concerned about the enclosure depth. Since the main Pro-10 PCB comes down between the footswitches a bit, I'm not sure that you would be able to "stack" the relay PCBs above it with the existing enclosure (1590BB) depth.

2. How would the relay bypass PCB wiring correspond with the Pro-10 PCB wiring?
For instance: each relay PCB has its own I/O, but the Pro-10 has two stomps/"channels" and only one set of I/O. The Pro-10 came with its own switch PCBs as well which I believe are just vanilla 3PDT boards but wasn't sure if there was anything extra going on there.

Anyhow, just a thought at the moment. If it wouldn't fit in standard 1590BB, I wonder if perhaps a 1590BB2 / BBS would have enough depth...

I have squeezed two relay bypass boards in a 1590BB. It was a bit awkward, but it worked. I stuck one under the board, and one over the footswitches. I insulated both sides because they would otherwise touch the walls of the enclosure.

Check out this build report to see how it looks:

Rainbow Barf.

Kind of like the Data Corruptor, I just had to try it. This one I could see using more often.

I was reading about the Rainbow Machine, and saw that it has intelligent switching for both stomps. Tap for latching, hold down for momentary. So at the last minute I decided to add it.

It was kind of a pain to shove both relay boards in. I used low profile electros for clearance and mounting tape for insulation. First I shoved the DPDT under the board.




Then I put the Bypass on the footswitches.



I put more mounting tape on the enclosure...

As far as the wiring, it looks like a standard ppcb bypass arrangement. Yes, there’s only one set of I/O jacks, but each side of the drive is an independent circuit with its own bypass.
