Gravity Wave (no audio)

[Masochist]

Just got my Gravity Wave all wired up but unfortunately I've run into an issue..

I'm getting audio when the effect is bypassed but nothing when engaged. I can hear LFO rate modulation in time with hiss/hum but that's all. I'm definitely plugged into the correct input/output. I've checked for solder bridges but I think I'm ok..all the 'bridges' I came across seem to be forgivable because they are attached to the same track.

I made the changes to components recommended to avoid dimension pot 'motor boating' of the Dimension pot. I think it was a 4.7uF MLCC and a 3.3nf cap in place of a 470nf and 330nf. Everything else remains standard. I've attached pictures of PCB front/back.

If anyone has any suggestions I'd love to hear them. Thanks
