Debugging EA Tremolo...

Removed them and tested it. No signal, harsh buzz. A learning experience for sure!

Here are some shots of the breadboard, if it helps at all.

As much as I can make out looks right.  If you have extra transistors, replace the ones on the board to see if one of them was bad.  (And put back R12 and C4.)  An audio probe would be very helpful.

Skip VR1 volume pot. Take the bare end from output jack tip-contact and touch it. Should make your amp buzz LOUD. Now connect that end to C3, where you disconnected VR1. Does that pass signal? Put your finger where C3 and R8 connect together. That should buzz (less because R8 loads-down your finger-buzz). Now touch each end of C1 and C2. That should buzz. OK so far? Lift the grounded end of R4 and stick it to Q1 gate. Touching either end of R4, or C1, or input jack, should buzz.
