Hey Crew,
Hoping someone has some thoughts on this. I've got a 69 Fender Bandmaster Reverb. The vibrato was really weak, did a recap, new trem roach, brought it back to life. However, the vibrato doesn't work on the slowest positions. It has to be set to about 4 to turn on. Below that, the light in the optoisolator stops flashing. If you have it set to 7 it sounds just fine, but if you turn it down to about 2-3 the light slowly dims and the vibrato stops.
Thoughts? Things to check? All the caps in that area are new, voltages look alright, and the resistors are the values they should be.
Thanks for reading this/for giving any insight you may have.
