In Phase & Out Of Phase Explained

Posted by crazyaboutguitars on January 14, 2012 at 11:10 AM

The information below was sent to me by Teye of Teye guitars. I asked him to put the information in laymans terms. He sent this the next day.In fact he sent a second E-mail that I will post after I paste this first E-mail He was in Spain visiting family and still took the time to E-mail me back. Teye always impresses me and I don't impress very  easily. You will be reading the real  "How It Works".


Extremely busy, added to which is at moment family life... am in Spain, trying to juggle everything.A quick attempt at explaining your questions -out of phase is best described as an honest attempt to choke the sound as if youwere choking the singer's throat. It is a very nasal sound where the pickupsactually fight each other instead of working together. The sound only works withtwo pickups (or more) on at the same time. The pickup that is wired out-of-phase is actually SUBSTRACTING its signal from the one(s) that are correctly phased.Especially useful if you have them on individual volume controls.Personally, I like this sound if done right. (And not over-used, but that's notreally in the hands of the builder)parallel:connecting the coils of a humbucker in series (the normal way, the ancient Gibson way) adds up the output of both coils and cancels 99.9% of hum. It gives a very strong signal, but so-to-speak the one coil is driving the other. The signal of each coil has to squeeze it self thru the other coil. You can also viewthis as that the impedance of the entire unit becomes twice as high as eithercoil by itself. Result: what we all know to be the typical HB sound: thick,loud, not so bright.When you wire them parallel, you lose the ADD factor (it's like connecting two1.5V batteries: in series they give 3V; parallel they give ...1.5Volt) but youalso lose the impedance doubling. Result: the tone becomes much less thick, andretai8ns much brightness.In a word: series - ROCK / parallel - TWANG Well, as a guideline.Hope this helps, hope you are well, hope everything is allright and you can finda way to hang in there with the circumstances!GreetingsTeye. [S.C.'s father had just passed away and Teye knew about it--Thus the reason for the last sentance.]

Second E-mail    ***************************************************************************

The actual DIFFERENCEa few attempts OOP sounds unnatural, PW sounds very natural OOP sounds funky all the time, PW only if you play a funk lick OOP sounds like an effect, PW sounds like a different brand of guitar. PW sounds like a country song. OOP sounds like some 70's country songs.OOP sounds constrained, as if your guitar is seriously ill. PW sounds like a fender. (some may not see the difference) Hope this helps and puts a smile on your faceTeye.


Okay, this is goig way over what I asked for. Teye's  taking the time to write it all of this is really cool to say the least. However he still won't send me the $32,000 guitar I want to review. {Yuk Yuk}

If you could send Teye and tell him how much he is helping the guitar community and that you found his information on this site -- --Teye has been in touch with me on and off ifor a strong four years. I consider him one of my best on line friends.

Just some helpful info on guitar hints (from another poster on Stew Mac)...this one on how to make a guitar nut "saw" from feeler gauge material: GREAT STUFF:

NUT CUTTING SAW (making one):

Make your own nut slotting saw (from a review)
Not wanting to plop down $$ for a set of Stew Mac razor saws, I obtained several strips of feeler gauge material from McMaster Carr Supply. I ordered these in thicknesses to match the string diameters of .010 - .046 strings. They come in 12" lengths and are 1/2" wide, tempered steel.

The cost ranged from about $1.10 to $1.50 each, depending on the thickness.
To make the gauge strip into a saw, I placed the strip in a bench vise with about 0.020" of the edge above the top surface of the vise. Then, using a small, very sharp cold chisel, I lightly tapped the chisel into the edge of the gauge strip at an angle, raising a small burr each time that would act as a saw tooth. Of course, you must be sure to make all the burrs face in the same direction. The burrs were as close together as I could make them, and covered only about 2" of the 12" length of gauge strip.

How did it work? Beautifully! Even better than I had hoped for. I started out with an 0.010" strip, just to mark the slot locations. The strip cut my Graphtec nut so well, I had to be careful not to go too deeply. The nut was in my bench vise, not in its slot in the guitar neck.

McMaster Carr Supply is a wonderful source of just about everything. They have the best on-line catalog I've ever used. The ship very quickly, and only charge actual shipping costs, never a "handling" fee. The feeler gauge strips are on pg. 2245 of their online catalog.


I have ordered three of the smaller slot-cutting strips today, mainly because the thicker slots are easier to smooth out (or deepen) than the small ones. For the larger slots (.020) and above, I use the discarded wound strings that I have rubbed in abrasive, and then slide the string back-and-forth in the slot, and finish off by using graphite or silicone in the slot. I also give the slot an extra .001 for my "touch" (i.e. .010 would be .011).
Smooth as silk!!

I recently traded an unused item for a Jay Turser (JT-200) Les Paul copy, thinking that I had basically never heard of it, and was a little hesitant about the deal. Long story short, this BEAUTIFUL Jay Turser (stunning yellow) with eight abalone/mother-of-pearl inlays left me out-of-breath! I still haven't found many reviews on this axe, but for those of you out there who pass this up are missing a GREAT guitar. I am beginning to head for it each time I have an evening of practice, and I have quite a herd, including another real "sleeper", the Epiphone AJ-200S acoustic...under $200, and what a guitar. I'm still catching my breath folks...give them a try! Dr. T
