adamcr Posted April 7, 2007 Report Share Posted April 7, 2007 Is there any obvious reason that the DC resistance of my cool rails PU would drop from 10 (ish) to 5 (ish) at the volume pot? Quote Link to comment Share on other sites More sharing options...
curtisa Posted April 7, 2007 Report Share Posted April 7, 2007 The volume pot is in parallel with your pickup, the total resistance will drop (resistors in parallel law). Although I would've thought it wouldn't drop by that much. Are you sure you've got the correct value pot in there, and wired up correctly? An undersized pot will cause the reistance to drop that much, and also reduce the available output too. Quote Link to comment Share on other sites More sharing options...
adamcr Posted April 8, 2007 Author Report Share Posted April 8, 2007 The PUs are an EMG SES (passive 'quiet' PU, resistance unknown) and an SD cool rails. The recomended volume pot is 250k which is what's installed. I've tried two pots, both 250k one cheap one expensive. Same result. I can't work this out at all. At the moment the output is far less (with a 10k ish SD PU) than my other guitar which is fitted with 9k ish P90s... Quote Link to comment Share on other sites More sharing options...
suicidecustom Posted April 8, 2007 Report Share Posted April 8, 2007 diagram of exactly how you wired everything or a detailed pic would help alot Quote Link to comment Share on other sites More sharing options...
adamcr Posted April 8, 2007 Author Report Share Posted April 8, 2007 I must have made a mistake, just rewired and all is as it should be. Sorry to have wasted your time! Quote Link to comment Share on other sites More sharing options...
