Built the Circulator board and tested it in the new Auditiorium platform (that thing is very helpful, highly recommend it lol), and I get no phase effect out. Signal comes out clear with the pedal on, so I'm assuming it has to be something with the LFO. I even took the LFO out of the circuit to make sure of this. Vcc and Vref values are correct on all ICs and there are no solder bridges, and everything has been reflowed to be sure. Changing the toggle switch from phase to vibrato results in volume reduction (since no dry signal survives in this mode, I assume), and no change is observed when changing the rate toggle. Board pictures attached, the silver in the lower middle isn't bridges, just silver sharpie from labeling the boards I got. Is there a way to investigate the LFO without an oscilloscope? Thanks in advance!
