coil tapping a 555

[Guest mgoetting]

I've got HRWs on my 555 and wonder how hard it would be to switch the pots and split the pups. I know it can be tricky working through the f hole.

 

Also, how would this sound on a 555? I have this setup on my Milly DC and like it.

Do you want them tapped or split?

I don't know much about this. Splitting drops out one of the coils, leaving a single coil sound. Tapping allows phase shifting between the coils and removes some of the middle frequencies.

 

Am I close?

 

If so, can I have both? My Milly is split I believe with a push pull pot that was setup at the factory.

I just recently discovered that the two are different.. I , like a lot of people, had used the terms interchangeably... thinking that they are the same.

 

coil split... Single coil / dual coil (humbucking)

coil tap... single coil with a choice of different amounts of windings... (full windings or tapped -reduced- amount of windings)

[Guest mgoetting]

So what about phasing? Aren't there some setup where you can run from series to parallel and carve out the middle frequencies?

 

I have no idea.

Seymour Duncan uses the terms interchangeably.

More confusion.

I think Coil tapping and coil splitting are the same thing. The idea is to separate the coil with the poles from the "hum canceling" second coil. This in essence gives you a single coil pickup (lower output, added hum, etc). The second pickup coil is "grounded" on both sides, so it does nothing.

 

Phase is a different deal entirely. The phase switch swaps the lead from one pickup. That swaps the polarity of one of the pickups so that you get a cancellation of some frequencies. If you roll the volume controls, it changes amount of the phase cancellation. My Guild S100 has this. Here's a link to the wiring diagram.

Hope this helps

It helps only if the bridge pup is the one with phase cancellation. Otherwise I'm lost.

Do a google search and you will see the difference is discussed in many forums...

I had thought that the two terms meant the same ...

Coil splits

Some guitars which have humbucking pickups feature coil splits, which allow the pickups to act as "pseudo-single" coils by either short-circuiting or bypassing one coil. The electrical circuit of the pickup is reduced to that of a true single coil while the magnetic circuit retains its original closed loop configuration. Usually, this feature is activated using a miniature toggle switch or push-pull switch on the tone potentiometer. Some guitars (e.g. the Peavey T-60 and the Fender Classic Player Jaguar HH) make use of a variable coil split circuit that allows the guitarist to dial a variable amount of signal from the second coil, from pure single-coil to full humbucker and everything in-between.

 

Coil splits are often wrongly referred to as a "coil tap". Coil taps are more commonly found on single coil pickups, and involve an extra hook-up wire being included during the manufacture of the pickup so the guitarist can choose to have all the windings of the pickup included in the circuit, for a fatter, higher output sound; or some of the windings in use and some "tapped off" for a brighter, lower output, cleaner sound.[/

I'm siding with you on this. It makes sense.

On the out of phase.. you have to have 2 pickups going and one is electronically backwards from the other... and they cancel out a certain amount of frequencies, creating a nasal sound.
