GreeneKing Posted January 5, 2009 Share Posted January 5, 2009 I just wondered if I'm missing something obvious here. I've had a Roland Cube 30 for a few years now and it's been a great little practice amp with aux input for the Tascam MP3 and headphone socket. I noticed that the lower strings were sounding a bit 'warbly' through it the other day and suspecting the bass battery tried 3 different basses all of which were the same. I've made sure none of the 'models' are on and that the FX knobs are zero'd. I've tried new leads, removing the Peterson tuner from the i/p, EQ is flat, compressor is off, I've removed the Tascam and even tried it on headphones but the 'warble' remains. It's really bad/unuseable through headphones. Any ideas? Maybe it's just knackered. Where's that thread re Line 6 practice amps again? I'd use my rig but no headphones and 500W might make annoy my neighbours in the flats a little. Am I missing anything obvious? Peter Quote Link to comment Share on other sites More sharing options...

I know you have on-board FX, but if you also have Fx out and Fx return sockets, you could use those to see whether the distortion is in the early stages, by plugging your Fx out into another amp, or in the later stages or main amp, by feeding a good signal into your Fx return. Hope that helps David Quote Link to comment Share on other sites More sharing options...
The Burpster Posted January 5, 2009 Share Posted January 5, 2009 do you have the gain turned right up? Mine used to do that with an active bass if I had the gain too high...... Quote Link to comment Share on other sites More sharing options...
GreeneKing Posted January 5, 2009 Author Share Posted January 5, 2009 (edited) I've tried all the settings and I'm 99% sure it's got a fault. By the time I transport it to a tech and get it repaired I suspect it's cheaper to replace it. GAK are doing the Peavey Max 112 for £125 delivered and it has a CD/MP3 input and may cope with low volume band practice. I don't need all the FX either. Peavey are usually ultra reliable too.
