Steve1954 Posted April 9, 2021 Share Posted April 9, 2021 (edited) As part of a p bass build I purchased some expensive pickups, pots and jack. This was some time ago so I don't remember the make. When I first put it together I couldn't get everything to work properly and so I switched out the pots for some others from a cheep harley benton bass. Everything worked ok but recently I had a bit of an earth buzz so decided to take the pick guard off and have a look. At this point I decided to refit the expensive pots and try and do a better solder job this time. So now, I plug the bass into the amp and get sound but when I turn the volume pot up or down it makes no difference. Testing with a multimeter at the jack and set to 200k resistance I get the following ... With volume down I get infinate resistance ... With volume up I get 10.1 Here comes the voodoo part. Even with the volume down and with infinate resistance I still get the same sound through the amp !!!! I have tried testing it with volume down and plucking a string. Same result. Infinate resistance but its still playing through the amp. How can that be? Next I disconected it from the tone pot in case that was having some effect. Still the same result. Desperate for some help here guys. Thanks in advance. P.S My best guess at the moment is the volume pot is faulty Edited April 9, 2021 by Steve1954 Quote Link to comment Share on other sites More sharing options...
hooky_lowdown Posted April 9, 2021 Share Posted April 9, 2021 Sounds like it's not wired correctly. Get a Ki0gon harness and save yourself the headache. 😃 1 Quote Link to comment Share on other sites More sharing options...

John Cribbin Posted April 9, 2021 Share Posted April 9, 2021 Were you watching, 'Can't Pay We'll Take it Away' while putting it together? It might have been repossessed ... I'll show myself out ... Quote Link to comment Share on other sites More sharing options...

Bigguy2017 Posted April 10, 2021 Share Posted April 10, 2021 OK... To start, make up a lead with a jack on one end, for your amp, and a pair of croc clips on the other end. This is most useful for fault-finding... Clip croc clips to pickup wires (pup disconnected from wiring loom). Is the pickup working? - That'll be a yes... 😉 Solder pickup wires to volume pot (outside pins). Clip croc leads to ground and centre pin - does volume pot now work? Solder output cable to pot (centre and earth). Connect a regular jack cable to the output jack - all working? Solder tone control and cap into place - still working?
