Amplifier Discussion / Roland cube 60
December 12, 2013, 01:27:21 AM
Trying to troubleshoot a hardly used cube 60 from the '70's.   Seems to have distortion or maybe reverb that won't shut off.  Speaker looks perfect and brand new.  No obvious burn marks or failures on the board.  Sprayed all the controls with cleaner and it's maybe a LITTLE better. I'll try it again tomorrow with some different guitar pickups[acoustic] and preamps and see if it's still acting up.  Any suggestions?

The Newcomer's Forum / Roland Cube 60

My cube 60 that I've had since the 1970's.  It seams to have developed distortion and bad sound where it shouldn't.  It used to be a VERY clean sounding amp. Now not so much.  Any suggestions on how to approach a fix for it?

Preamps and Effects / preamp for K&K
November 20, 2013, 04:27:54 PM
I just had a K&K pickup installed in an acoustic guitar and it turns out I need a preamp that is impedance matched for the pickup.  My understanding is that means K&K, Ultrasound, or maybe Redeye.  Any others I should consider?
