Zenitram Posted March 24, 2014 Share Posted March 24, 2014 When the tone pot is all the way down, the bass plays fine. Increase the tone, to make it treblier, and it's fine, and works, until it reaches the very end, when it's most "on", or most open, or most trebly, and the sound cuts out. Roll it back a bit, and it works again. Any ideas? I have the bass in bits and the wiring seems okay. Can post a pic if it helps. Thanks.

JapanAxe Posted March 24, 2014 Share Posted March 24, 2014 The wiper is losing contact with the carbon track inside the pot at the end of its turn. Sounds like time for a new pot! Quote Link to comment Share on other sites More sharing options...

gary mac Posted March 24, 2014 Share Posted March 24, 2014 Sometimes it is possible to rectify this fault by carefully bending the wiper. there are a number of vids on You Tube that will show you how. But if you are not worried about preserving the original pot you may as well just splash on a decent quality replacement. Quote Link to comment Share on other sites More sharing options...
HowieBass Posted March 24, 2014 Share Posted March 24, 2014 Is it possible there's an accumulation of 'crud' at the end of the track causing the bad connection? Have you tried spraying switch cleaner into the pot to see if that helps at all? Quote Link to comment Share on other sites More sharing options...

[/quote] That's OK up to a point, but to have accumulated that much crud then it's likely that a lot of it is going to be the carbon track of the pot anyway. It might buy a few months grace though, so no harm in trying. Quote Link to comment Share on other sites More sharing options...
Zenitram Posted March 25, 2014 Author Share Posted March 25, 2014 Well, I solved the problem. This is what I did to solve it, in case it helps others who read this: I took the bass to bits, looked at the wiring, saw that it all seemed good, wondered about de-soldering it all and rewiring it up again and replacing the pot at the same time, decided against doing any of that, put everything back together again having basically done nothing, and the problem has now gone and it sounds great and works perfectly. Thanks for all your help everyone. Quote Link to comment Share on other sites More sharing options...

HowieBass Posted March 25, 2014 Share Posted March 25, 2014 (edited) You probably scared the bass into thinking it was going to be parted out so it decided to stop pissing about and behave itself. Edited March 25, 2014 by HowieBass Quote Link to comment Share on other sites More sharing options...
