Re: 3 or more Humbuckers in a Guitar?
My main guitar right now is a 3 pickup les paul custom, and I agree with the previous posts...three humbuckers looks cool but the stock configuration does not sound cool, and all three on at once is pretty useless. I've tried a few configurations, but the one I am very happy with now is a humbucker in the bridge (in my case, a pearly gates) and two PhatCats (essentially giving an "HSS style" configuration on steroids).
I like this configuration better than a standard les paul (for me). I don't find that the middle pickup gets in my way while picking, but I can see how this would be an issue for some people. I think the pearly gates and the phatcats go well in an all mahogany guitar, too (they are all pretty bright, so I feel they blend nicely with the guitar).
If you are interested in how I have it wired, read on.
Now that I am not afraid to solder, I have tried a bunch of wiring options. I have the Neck HB and Bridge PhatCat wired "normally" to the three position toggle. I have the middle PhatCat on a push-pull pot so I can add it at any time (adding this to the bridge or neck gives a slightly "honk" kind of sound...not a strat, mind you, but in that "in between" setting tone family).
Furthermore, I have the 3 position toggle routed through a push-pull switch, so I can remove the neck and bridge pickups whenever I want (putting the two push pulls up gives middle all alone--this also gives me a kill switch for the guitar). It sounds complicated, but it is very straightforward to use. Finally, I have the pearly gates wired to a third push pull for coil cut, but I rarely use it. I have not done anything with phase...so far, I don't feel the need.
