Home Forums GuitarPCB Build Support Apollo Tremolo – no effect Reply To: Apollo Tremolo – no effect


fr4nck – I would venture a guess that there is a wiring issue. Double-check that the HOT signal wires to and from the PCB are connected to the pads directly next to the little “T” that is screen printed on the input and output points on the PCB. I tried to examine the photos provided, but I was unable to make out to what connection points they terminate.

The video “sounds” to me like the PCB is not getting any signal input, but the output ‘sounds’ as tho it is correct because of the noise indicators as you adjust the pots.
