On my Epiphone Les Paul, if you have the switch in the middle position and you turn one volume knob all the way down, both pickups will be silent. This sort of problem is discussed on this page: It says this will happen if the Les Paul is wired as you would a Fender. Apparently, this wrong way is the way Epiphone does it (a guy I was talking to at the guitar shop said all Epiphones did it). My question is if having the volume cut off when one knob is all the way off is the only problem with this coupled volume knob setup (in which case I don't really care about it), or will the knobs not work quite right in other ways? One reason I ask is this... let's say I have all the knobs turned to 10, except the rhythm tone knob is down to 0. This creates a pretty good sound for me when the distortion's cranked up, and goes perfectly with a half-rocked wah pedal for that "Money for Nothing" tone. Now let's say I roll off the rhythm pickup's volume from 10 to 9. All of a sudden there's a very drastic change in tone, and it sounds a lot more like the treble pickup by itself. Of course one would expect this from rolling back the rhythm volume knob, but not from 10 to 9. Rolling the treble's volume from 10 to 9 instead fattens the sound as one would expect from my out-of-phase pickups (I did the Peter Green mod of flipping the magnet), but doesn't make so drastic a change. Do you think this is because of the coupling, because of something else, or is this actually normal for a Les Paul? - Kef

...Do you think this is because of the coupling, because of something else, or is this actually normal for a Les Paul?... coupling. actually normal for a Les Paul this wiring arrangement. BTW there are other demons involved when you wire it "like a Gibson"

Other demons? What do you mean?

Other demons? What do you mean? I think UnklMickey went to get some ZZZZZZZ's. I'm no expert (I don't own a Les Paul-type axe yet, and I don't know all that much about wiring), but I've seen the situation discussed in several places. The quickest reference I found with Google was www.singlecoil.com/docs/paula.pdf. Dirk (he's in Germany) just kind of touches on the subject, but you can get an idea of some of the "demons" that UM mentioned. Hope this helps until somebody more knowledgeable can chime in. -- Doug C.

So the knobs are "supposed" to be coupled? Very interesting, though it does make them behave rather strange when the switch is in the middle position, which is the position I almost always use...

Other demons? What do you mean? ..........I think UnklMickey went to get some ZZZZZZZ's. ... evidently i should have gotten some ZZZs much earier. i was juggling responses to several threads at the same time and ended up giving some advice to your problem somewhere else. -- WTF! _____________ "i just had a thought. i'm interested in seeing what the results would be if 47k (or maybe 100k) resistors were placed in series with the wipers of the volume pots, and the cables that go to the selector switch in a 2 volume configuration like yours. my theory is that it will minimize the coupling without the pickup loading that would occur if the pots are wired bass-ackwards like many 2 volume Gibsons are. are you game to try this? " guitarnuts2.proboards45.com/index.cgi?action=display&board=wiring&thread=1129056191&page=1________________ JohnH had some things to add, so follow that thread to it's conclusion. Sorry for the confusion i've created. the other demons i spoke of have to do with the increased loading of the each pickup, when it's volume control is wired backwards. this causes the highs to roll off when the volume is reduced. it's not that hard to do. just exchange the "high" and wiper connections on the volume pots. if you don't like it, it's just that easy to put back to "stock".

So the knobs are "supposed" to be coupled? Well, somebody at Gibson many moons ago apparently thought so, anyway. And it looks like Dirk thinks anything different is "less than optimal." Annoyin', ain't it? I wouldn't be surprised if some of the other members here have good suggestions for a way (or ways) around it. -- Doug
