Metalgoth Posted November 23, 2004 Report Share Posted November 23, 2004 Perhaps I can get an answer here. I recently dropped some EMGs into my Nuno, then took them out later because I wasn't happy with them. That requires different pots, etc, so when I put the old stuff (Washburn passive pickups) back, I substituted a 500k push/pull volume pot that I got from Stewmac months ago for the original factory push/pull pot. I followed the Duncan wiring diagram for 2 hums, vol, 3 way switch and coil split, and finally got it all together working as it should, with one exception: the volume control only turns down the volume slightly. If you turn the knob all the way from end to the other, you hear the volume change slightly. Wha' hoppen? Did I get a bad pot, or is there some mistake in my wiring?

westhemann Posted November 23, 2004 Report Share Posted November 23, 2004 i think you overheated it Quote Link to comment Share on other sites More sharing options...
Metalgoth Posted November 23, 2004 Author Report Share Posted November 23, 2004 Ohhhhhh..... I am a bit clumsy with the iron... I was holding it in my hands, but it did get pretty hot to the touch while I was working. I guess a heat sink and quicker work is in order.

mj_gant Posted November 23, 2004 Report Share Posted November 23, 2004 Is the end lug being fed from your switch or pickup? Is the middle lug going out to your jack? If you mix these two up...you may experience something like you describe. I have never fried anything and I use a 40 watt iron, I cook things for way longer than I should at times and have never fried anything...especially a pot. You'd really have to cook that thing to kill it. Double check your wiring with a fresh and carefull outlook. Quote Link to comment Share on other sites More sharing options...
westhemann Posted November 23, 2004 Report Share Posted November 23, 2004 You'd really have to cook that thing to kill it. true...but the key is that he reused it.the repetitive heating and cooling is what kills them in my experience.

jer7440 Posted November 23, 2004 Report Share Posted November 23, 2004 so when I put the old stuff (Washburn passive pickups) back, I substituted a 500k push/pull volume pot that I got from Stewmac months ago for the original factory push/pull pot. He wasn't reusing the pot . Quote Link to comment Share on other sites More sharing options...
Saber Posted November 23, 2004 Report Share Posted November 23, 2004 (edited) Is the "counter-clockwise" lug properly connected to common? Otherwise that would produce the effect you're getting. Edited November 23, 2004 by Saber Quote Link to comment Share on other sites More sharing options...

Metalgoth Posted December 1, 2004 Author Report Share Posted December 1, 2004 LOL Well, lemme double check what I've got going on in there. I was following a Seymour Duncan diagram, but maybe I read it wrong. Quote Link to comment Share on other sites More sharing options...
lovekraft Posted December 1, 2004 Report Share Posted December 1, 2004 It sounds to me like your pot isn't grounded, so it's acting like a series resistance instead of a voltage divider. That would explain what you're describing, but it's at best just a guess. You can check the pot with multimeter to see if it's toast, but you'll have to disconnect it from the circuit. If it reads close to 500K between the two outside lugs (shaft facing you, lugs up), reads very low from center to left and near 500K from center to right at full CW, and near 500K from center to left and very low from center to right at full CCW, it's perfect. HTH. Quote Link to comment Share on other sites More sharing options...
