Finally got mine boxed up. Thanks to Stephan for the board and Brett for the beautiful box artwork.
The toggle switch pads on the board didn't line up with the box artwork, but that was easily fixed by wiring the switch to the board instead of soldering it directly. I had to mount the board higher, so I used solder lug pots and connected the pots to the board with some stiff solid wire.
This board has a shit-ton of gain. I run mine with the Gain Trim turned all the way down.
This is a v1 board. I did the "squeal reduction mod." It helped, but did not completely eliminate the squeal at high GAIN & VOLUME settings. I have some V2 boards and will see how they do.
The relay controller runs the Coda Effects code which toggles the relay when the stomp switch is released. I worked around that by swapping the switch with its 10K pull-up resistor. Now it toggles the relay when the switch is pressed. It got me to thinking about modding the code. Then I came to the conclusion that a microcontroller is complete overkill here and the 555-based relay driver is a better way to go when we don't need a bunch of fancy features. Below is a slight mod to the PedalBCB basic relay bypass. The open-collector DISCHARGE output (pin 7) has greater current sink capabilities than the the OUTPUT (pin 3), so I use that to drive the relay. This circuit is compatible with 4.5V, 5V & 9V relay coils simply by changing R4. C1 does not need to be film; aluminum and tantalum caps have a smaller footprint. The only time this circuit needs a regulator is if someone wants to run the pedal on something higher than +15V.
BTW, there is nothing magic about the values of R1-R3 & C1. I tried 1M, 100K, 100K & 220nF and they work great.
