I have a MM RD 115, Chassis no: 2275-65
I don't have the RCA pedal for this amp (looking for one right now!) and have noted that the vibrato on the amp doesn't work. When I crank up the volume and short out an RCA to the vibrato pedal input in the back of the amp, I can actually hear the hiss going through the vibrato. However, any instrument going into the channel doesn't get vibrato at all. I have read that there is a trim pot that might need to be turned up in the chassis - where is that located?
Thanks for reading this!

Not sure on the RD's, but if it's in the same area as the HD's, it's on the preamp board, on the end by the bias pot. |
