johnny_frog Posted March 1, 2010 Share Posted March 1, 2010 Hello all, my wee roland cube 30 has started acting a little strange, she's coming up for 2, any help/advice would be much appreciated... It started at the weekend when i noticed that the delay/reverb effect wasn't working. Took it into the lab at work today and stripped her down for a look see... and couldn't see anything. The discrete componants on the board all looked ok and there were no signs of any blown tracks or burnt wires. so as i don't use the delay/reverb effect i thought "nevermind" and put it all back together again and took her home. started using her tonight only to find that the delay/reverb is now working, (although the led that is supposed to light up still doesn't) however... now the 'models' won't switch off... I kind o think she is sulking cos I brought home a Laney combo from that nice Mr. Thornybank's house on saturday. Anyway, if anyone has had anything similar happen and has a fix i'd be very grateful if they'd share. many thanks Frog Quote Link to comment Share on other sites More sharing options...
Ancient Mariner Posted March 2, 2010 Share Posted March 2, 2010 It's likely that one or more components ha a dry joint or is breaking loose from the PCB. Being moved around and particularly vibration can do that to lighter weight circuit boards. The other possibility is that it's a software issue, in which case it may just need a hard re-set (assuming it has the facility). Quote Link to comment Share on other sites More sharing options...
johnny_frog Posted March 3, 2010 Author Share Posted March 3, 2010 Figured it might be something like that when there wasn't anything visibly wrong with any of the capacitors or resistors. Thanks for the assistance. Quote Link to comment Share on other sites More sharing options...
The Burpster Posted March 3, 2010 Share Posted March 3, 2010 I have a spare amp part if you wish to take it off my hands....... Although if I remember rightly it has a similar fault and thats why I was gievn it. the cab now houses a PJB `D-200 and a celestion speaker.

I only use the roland in the house because it has the headphone jack which means I don't have to subject my beloved to my amaturish plunking. When i get time (prolly around the 6th of Octember) was thinking of stripping the whole thing down and seeing if I can just bypass the whole effects/modelling side and got straight from the tone controls into the amp... it's starting to smell like another project which will linger.
