SOLVED Spatialist Reverb

[cable-effect]

Looking for some help on this build. It seems to be 99% working but the dwell control does not seem to affect anything. All other controls seem to be fine.

If you have a DMM measure the voltage on pin 2 of the Dwell pot with the knob at minimum, then again with the knob at maximum.

It should sweep from around 0V to around 3.3V.

That's exactly the reading I'm getting. Any chance it would be a solder connection on the FV-1?

Sorry. Forgot! I realized after I built this that the 1uf caps I used should have been mlcc..

Anything sticking out to anyone or have another recommendation?

See if all your solder joints look OK like the ones marked ok on this image.

Yep, that's where we were headed next.

Touch up the solder on these three pins. The middle highlighted pin is the POT0 input to the FV-1 (Dwell pot).

That's perfect. That's what I thought from looking at the schematic. Tried reflowing them before posting initially but will try to clean those up. Thanks!

That did it. Working perfect. Thank you!
