petetexas Posted February 25, 2018 Share Posted February 25, 2018 (edited) Last night my Carvin bass head started fading in and out while doing the sound check . Luckily , I always carry a spare . After the sound check with the spare , I went back to the Carvin and it worked for the rest of the gig with no problem . Cleaned all the sockets , checked all the leads .....all seems ok .....ran it for about on hour this morning ......ok Anyone got any ideas as to the cause ?

mart3442 Posted February 25, 2018 Share Posted February 25, 2018 Possibly the capacitors failing....... Quote Link to comment Share on other sites More sharing options...
alembic1989 Posted February 28, 2018 Share Posted February 28, 2018 I had the same problem with my Ampeg sv200t. I took it to Surrey amps, who did a major refurb...but it still happened..they took it back checked it again and said there's nothing wrong with it?? To this day it still does it..but I've noticed that it does it if I haven't usd it for a few weeks. ....if I use it regularly it seems to sort itself out, and sounds great. No idea why that happens... Quote Link to comment Share on other sites More sharing options...
petetexas Posted March 2, 2018 Author Share Posted March 2, 2018 Monday I cleaned ( switch cleaner on a spare jack , inserted in /out ) on all the sockets on amp - front and back . It has been running for almost a total of 6 hours ( with and without bass being used ).............NO cut in / out or fading .......... I will see on next gig ( in 2 weeks time ) Pete Quote Link to comment Share on other sites More sharing options...
MoonBassAlpha Posted March 6, 2018 Share Posted March 6, 2018 Did you clean the send/return sockets too, as they can be the culprits, especially if you don't use them as your effects loop. Literally today I was informed that I had remotely "fixed" a Marshall ValveState by suggesting he put a patch lead in send/return loop. Amp whisperer, anyone?

petetexas Posted March 7, 2018 Author Share Posted March 7, 2018 Carvin has not cut in / out / faded at all for a week . Just to be on the safe side , I have taken it to a Amp tech for a full service . Told him what had been happening - straight away he said it was probably dust etc on the contacts .
