samdjr74 Posted March 6, 2004 Report Share Posted March 6, 2004 Hi All, I have a custom made explorer running two SD humbuckers wired like a les paul. The problem is the tone on the bridge pick up is acting like another volume but I don't have the same problem in the neck postion. The 2 way is a right angle switcraft and the pots are gibson long shaft. Any idea what the problem might be? Thanks, Sam Quote Link to comment Share on other sites More sharing options...
weezerboy Posted March 6, 2004 Report Share Posted March 6, 2004 have you checked to see if there are any lose wires / wires crossing inside? Quote Link to comment Share on other sites More sharing options...
samdjr74 Posted March 6, 2004 Author Report Share Posted March 6, 2004 yep, 2 times and I even rewired it. Same problem with a different schematic so the issue must be the hardware but where do I start? Quote Link to comment Share on other sites More sharing options...
weezerboy Posted March 6, 2004 Report Share Posted March 6, 2004 i'd say replace the pots, they aren't exactly expensive but don't quote me on that Quote Link to comment Share on other sites More sharing options...
PxP Posted March 6, 2004 Report Share Posted March 6, 2004 Did you check the capacitor connected to the pot? Quote Link to comment Share on other sites More sharing options...
Scott Rosenberger Posted March 6, 2004 Report Share Posted March 6, 2004 it sounds to me like the capacitor value may be wrong. Make absolutely sure they are the same for the bridge and neck tone pots Quote Link to comment Share on other sites More sharing options...
Saber Posted March 6, 2004 Report Share Posted March 6, 2004 Like PxP suggests, if the capacitor is defective (short), it would cause your problem. Try switching the bridge and neck capacitors. If the problem follows the capacitor, then there's probably something wrong with it. Otherwise, switch the two tone pots and so on...

ansil Posted March 6, 2004 Report Share Posted March 6, 2004 what is the actually value stamped on the capacitor.. or printed on there.. for gutiars.. if it is too high then it will act like a volume control and or a gain control instead of a tone. even when the capacitor is functioning normally. also if you want ot see the freq roll off you can use this online calculator to show you the drop of points http://www.muzique.com/schem/filter.htm theres alot of usful stuff on this site you should definately check it out. personally iuse a 1meg and a 1mfd cap but i like the gain control effect that it does..

samdjr74 Posted March 10, 2004 Author Report Share Posted March 10, 2004 Hi All, Here's what I've done: Replaced both the volume and ton pots on that humbucker with brand new ones Replaced both caps with brand new ones, both .47 Rewired the guitar completely. No change but here's my thought, the neck pick-up is a SD pearly gates model while the bridge is a SD dimebucker. The bridge is much hotter then the neck, could it be that I require a different value cap for the bridge because it is so much hotter?

Nah, the characteristics of the tone control depends solely on the values of the cap and the pot. It should sound the same for all pickups. Has it ever worked before?

samdjr74 Posted March 10, 2004 Author Report Share Posted March 10, 2004 It worked before some what ok when I was running through a 5-way rotary switch but the tone rolloff was never great. I decided to change out to a LP 3-way for ease of use. I've even changed the 3-way to see if that makes a difference but it doesn't Quote Link to comment Share on other sites More sharing options...
PxP Posted March 10, 2004 Report Share Posted March 10, 2004 Weird. If you could sketch a wiring diagram for us, it would be helpful. Quote Link to comment Share on other sites More sharing options...

PxP Posted March 10, 2004 Report Share Posted March 10, 2004 Looks ok. Try a smaller cap (like you suggested earlier). If the pickup sound has more bass and less treble, a smaller cap might work. Try 0.33 or even 0.1. Quote Link to comment Share on other sites More sharing options...
samdjr74 Posted March 10, 2004 Author Report Share Posted March 10, 2004 Would it be ok to mix cap values between the 2 pick-ups? Quote Link to comment Share on other sites More sharing options...
PxP Posted March 11, 2004 Report Share Posted March 11, 2004 Would it be ok to mix cap values between the 2 pick-ups? Sure, go ahead and experiment! Quote Link to comment Share on other sites More sharing options...
