rg 120 Tremolo not Tremoling
« on: April 22, 2017, 02:58:49 PM »
Bought a Commander 1 and the tremolo is not working, both the speed and depth knobs don't do a thing, therefore the fault lies where they share a common fault.
Could this be an issue with the small electrolytic caps?

How do I attach an image from my HD? The attachment option doesn't seem to work.

Ok boys, one at a time, I can't keep up with all these replies.

Figured it may be the LDR (opto-coupler) then with my meter I realized there was no voltage going to it, now I suspect a bad transistor in the tremolo circuit.

Seeing that this was from months ago, I wonder how the Tremolo is now?
