I have an Epi 335 Studio (1 vol, 1 tone, 3-way) that someone put Burstbuckers in before I bought it. The problem is that they're out of phase in the middle position. Can someone tell me what I need to do to get it in phase. If I recall, it's a simple as switching some wires around. I don't want to bother reversing the magnets. Thanks in advance.

Do the burstbuckers have four wires each plus the braid? If so, yes it is easy. For each pickup there should be two coloured wires joined together, and one to ground and one to hot, plus the braid is grounded. On one pickup, just swap the hot and ground coloured wires.
If however, the pickups are just a braid with a single internal conductor, then the only good way is to flip one magnet (rotate about its long axis, so the positions of the two long thin edges are swapped).

Yeah, BBs just have a braid with a conducter. Though someone added some wires, it seems, to make it out of phase. It looks like it was on purpose.

I have an Epi 335 Studio (1 vol, 1 tone, 3-way) that someone put Burstbuckers in before I bought it. According to Gibson, there are three different configurations for a Burstbucker. You can pull down a wiring diagram hereYou should be able to fix this without disassembling the pickups. Without knowing exactly what you have, let me defer to what Gibson says in the wiring instructions referred to above: "Note: If pickup is out of phase with existing pickup, reverse black and red leads"If this doesn't do the trick, then please take some pics (focused, please) or draw up a quick sketch. This will go a long way to getting a solution if the cheap and dirty fix above doesn't do the trick. Happy Trails Cynical One

EDIT Dang, I've NEVER had 3 responders jump in while I was a'typin'. Are the Burstbuckers 4-wire? Is at least one of them 4-wire? If not, there is little that you can do short of pickup surgery. If one is 4-wire, you can reverse the wires. How are the wires on each (or at least the 4-wire) pickup connected? This determines HOW the wires will need to be reversed. Now this gets into the process of building model ships in bottles. Or, brain surgery thru a nasal passage. You will need to take things out of the body, It's very hard to get them back in. Before you start this, you need to have long conversations a'board with folk that have endured such tribulation. One thing that I like to do is to fasten a piece of thin mono-filament fishing line to each control's shaft, switch, or jack BEFORE it's removed from the body. Let the fishing line feed thru the hole that you are removing each component from. tie it securely to the shaft after you remove the knob, nut, and flat washer but before it is allowed to fall thru the body. I like to loop it around a couple of times and thru the shaft slot below the splines. Make sure that they're long enough ( a couple of feet each) and fasten something to the other end to ensure that it doesn't fall thru as well. I wouldn't use a roller skate as it might scratch the finish. A wooden or plastic thread spool works fine. To be fair, since things are removed often thru the pickup openings, it's a large nose. Now, if this has the Epi connectors for each pickup AND one is 4-wire, you may be able to remove one pickup, unplug it (remember to use a line (fishing or otherwise) to secure the other end of the connector that is part of the internal wiring harness, and change the wiring to the connector (or make a transition cable that plugged into each. I have no idea what's in or has been done to the guitar, so you'll have to look, take pics, and post before much further help can occur. guitarnuts2.proboards45.com/index.cgi?board=reference&action=display&thread=3190

Well, as I was alluding to and other's have said, out of phase on a single conductor plus shield pickup is problematic to do. It means that at least one shield is being used as the hot lead. If both pickups are truly not out of phase with each other, correcting (as in removing) the additional wiring added should restore things. Good, I've been concerned about random acts of soldering lately.... ;D

It's wired up like this. Hope my drawing makes sense.

On the Epi 335 Studio, the controls are right by the F hole. I can easily put them back in. Now messing with the output jack is another story, haha

Even if someone could just post the proper way to wire up Burstbuckers (it just has one wire with a shielded outside and hot lead inside) with 1 vol, 1 tone and a 3 way. That would be fine by me, instead of trying to decipher how it is currently.
