Simulcast No Effect

Hey y'all,
My simulcast is passing audio in bypass and, when switched on, the LED lights but the pedal doesn't pass audio. I've reflowed my solder points, double-checked component values and orientation, and looked for any shorts. I've also swapped out the chip with a MAX1044 and a 7660 to no effect.

Only thing I can think of (except something obvious that I'm overlooking) is that my OC71 sub isn't working/compatible? After reading some threads here I picked up a GT402B from Stomp Box Parts with an HFE in the 90s, and double-checked the odd pinout with their diagram and Small Bear's (in the attached photos).

Any ideas? Thanks so much for the help!
