  1. Sorry Vomer there is no way a that the double stacked switching Epiphone push pull volume controls will react the same way as the Gibson style 500k pots, like the Gibson ES-339 uses. I have replaced Epiphone push pull volume controls with the larger sized 500k pots and not have the coil tap function. The Gibson/Epiphone style 500k's have a larger radius sweep, are much smoother and don't drop off so quickly. However, on a 339 it is not a simple thing to replace them and if you can live with the way the stock Epiphone push pull pots work its best to leave them alone.

    None of that explains the situation albatross describes. You're confusing a relatively simple wiring difference with the nuances of pots.

     

    "50's style" wiring = independent volume controls.

    "modern style" wiring = in the middle position "if EITHER of the volume controls is set to minimum there is no output at all."

  2. Welcome Albatross. Sorry mihcmac but what you said is not correct. It doesn't matter what pots you use or whether there is coil tapping, it is to do with the 'style' of wiring. Usually referred to as 50's style or modern style. There's a Seymour Duncan blog post which explains it here....

    Edit: that's not that well written, but it gives the general idea. You could google for similar and get a clearer picture.

     

  3. Hello Lord S. Good to see a familiar face!

     

    Hi apoc, yes, lots of previous threads here. My 2 cents, the 5102T was also released as the EA250, I believe it was the earlier version, some of which which had different 'staple' pickups. As Lord Summerisle said, definitely made in Japan, not the USA. Many of them had a Made in Japan sticker on the neck plate. I have an EA250, it's a very pretty guitar, I like the sound when it's boosted a bit, the pickups are very low output but give a nice retro 60's tone. Great action and very easy to play with the slim neck.

  4. Are you getting any sound from the bridge pickup when the selector switch is in the middle position, and both volumes are turned up?

     

    If so, this is normal, and both volume controls will affect both pickups with the switch in the middle position. There are two basic ways to wire 2 humbuckers/ 2 vols which will either have the volumes operate this way, or have 'independent' volume controls.

     

    If you aren't getting sound from the bridge pickup when the selector switch is in the middle position, and both volumes are turned up then something else is happening. Let us know what happens in each switch position?

  5. Yes, welcome and thanks for the info, very useful to know.

     

    I looked up a seller and the bridge is described as having, " A receiving hole for M4 Studs is designed as a "slot". Therefore, our bridge fits as a replacement for stud spacing of 72.6 mm to 73.6 mm (center to center)."

     

    Obviously some room in those measurements. Glad to hear you got yours sorted.

     

  6. Open. 12th. After both right, 3rd. 15th. On my guitars, for the most part, once the open and 12th are right, any other 12 fret distance is either right on, or off by, and this is important, the same amount. So if open and 12 are right, but 5th and 17th are both just a smidge sharp, that's fine. If 3rd and 15th are off and different, which hasn't happened much at all to me, it's usually the nut that is wrong.

     

    Thanks, interesting, never come across that. I'll try it.

     

    not even the 5th/7th that most guitar players use.

     

    I'd heard this wasn't a good method, physics and the imperfect nature of pitch vs. string length.

     

    it is entirely possible to have a G string nut slot stop the string too close to the first fret, that is, too close to the pickup side of the guitar.

     

    Yes if we take it to the realms that Buzz Feitin does. But for us ordinary mortals with ordinary nuts, I'd still stand by the usual method of having the strings leave the nut at the edge by the fretboard.

     

     

    The node at which the harmonic is strongest is what I guess we would think of as the actual center of the string when stopped by the nut right now and the saddle right where it is. That can often be somewhat forward, pickup side, of the actual fretwire, and it can be aft, nut side, of the actual fretwire, too far back in the space to fret it without affecting the tuning.

     

    What I understand from this is that if you set the intonation using your method which gets you playing in tune along the neck, you might find 12th harmonic doesn't equal 12th fretted. Whereas I would be starting from that point, and trying to make everything work from there.

     

    We want to set the guitar so that when we fret at the 12th we are fretting at the center of the string, as exact as we can, which isn't very. If we divide the string (almost) exactly in half, both sides of that half will be (relatively) in tune with the rest of the guitar, and in tune with the other instruments that were tuned with the same reference.

     

    No argument there, that's what we're aiming for. Thanks rct, interesting stuff.

  7. One of us can intonate a guitar without using harmonics.

     

    Could you tell us your method?

     

     

    One of the dangers of using harmonics is that they begin sharp and can take quite a time to even out.

     

    Sorry, I don't understand this. By definition, the 12th fret harmonic is the octave of the open string. How does a harmonic "begin sharp"?

     

     

    If the string stops too close to the first fret the string will intonate sharp, therefore, the string is stopping too close, NOT too far away. Sharp = short, flat = long.

     

    The string can't "stop too close" to the fretboard if the nut is in the correct position, and if the frets are in the correct position. As I said above, if the nut is cut incorrectly so the string leaves the nut somewhere further back than the fretboard edge of the nut, it will affect the intonation of the guitar; the frets will be relatively "in the wrong place". This is why:

     

    Imagine we have a guitar with a moveable nut and moveable frets. Lets say we start out with a scale length of 30". The 12th fret is half way along at 15". If we move the nut 1" towards the headstock to give a scale length of 31", then the 12th fret will need to be moved the same direction by 1/2", to 15 1/2". If we move the nut but don't move the 12th fret and leave it at 15" from the bridge, the string fretted at the 12th fret will be 1/2" short, and sounding sharp relative to the octave and the octave harmonic.

     

    This is why mfowler should check his nut, as this is his symptom, the fretted 12th note sounding sharp relative to the open string and the mid-string harmonic.

     

     

    The harmonic is too near the center of the string, a place we can't fret, to intonate to.

     

    Could you explain this further? The centre of the string being the 12th fret, a place we can fret, or am I missing something? Thanks.

  8. Harmonics will elude you. Forever. Don't use them.

     

    You can't intonate a guitar without using the harmonic at the 12th.

     

    May have to turn the saddle around if it will give you enough room to go back some more.

     

    This will only affect the intonation, not mfowler's problem.

     

    If not that, nut may be stopping string too close and have to be re-done or replaced.

     

    Not too close, too far away. I should have remembered this, check where the string leaves the nut- it should leave at the edge closest to the fretboard. The slot should be cut with a downward sloping curve away from the fretboard edge of the nut.

     

    If not that, the string gauge you are using won't intonate on that guitar. If not that, bridge in wrong spot! It happens.

     

    It's not about the intonation. So, the bridge isn't in the wrong place.

  9. If you are intonating a guitar you rightly compare the harmonic at the 12th fret with the fretted note at the 12th fret.

     

    If the fretted note at the 12th doesn't match (i.e. be the octave of) the open string then a number of things could be happening:

     

    1) the 12th fret is in the wrong place (not likely if half your strings are working OK, and not very likely anyway);

    2) the 12th fret could be acting as if it were "in the wrong place" by how it has been skimmed and crowned (or not crowned)- a wide flat fret may be wide enough for the fretted string to leave the fret at one edge rather than the middle;

    3) you could have dodgy strings if they are an old set, and you could struggle for ever to make any sense of their intonation;

    4) you may be pressing down hard on the unwound strings and sharpening them without realising it. Particularly if your action is a bit high, and/or you have high frets.

     

    My money would be on 4, and 3 if you have old strings. If they are old, just get new ones and see how they work.

  10. Hi, welcome to the forum. You are quite specific about the spelling of the name; does it appear somewhere on the guitar? If you hadn't been so specific, I would have been asking, is that spelling Sorrento?

     

    Pics would be useful.

  11.  

    I found out that when I printed it off' date=' the scaling was off by 1/16" of an inch based on

    the 1" thick line that is supposed to be a reference.

    [/quote']

     

    You have to make sure you print onto the right size paper, re. the instructions on the site.

     

    And I avoided the cutting and sticking by printing onto card. They work fine, and they seemed very accurate when I checked against radii I knew. Sorry I don't understand the need for measuring the centre of the curve, a curve is a curve surely, using any part of the curve of the gauge will read the same.

     

    I've replied to these points as I wouldn't want anyone to be put off having a go at using Pickguardian's free download-and-print gauges, as I'm interested in hearing hat radii other folk have on their Epis, particularly their Sheratons.

  12.  

    How do you like it?

     

    My previous main guitars were two 7.25" strats, and I was looking for a strat when I bought this. (On long holiday, needed a gtr.) The overall feel of the neck is so good that the radius doesn't bother me. Funny though, reading flat radius specs on desirable axes like the 3x P90 Fret King Esprit still puts me off. And now I'm just a little jealous of other Sheraton owners with bigger curves, so to speak. But mine is definitely a keeper, and I play it a lot.

     

    Ricochet, no sign of any fretwork or boardwork. All the binding and inlays are good.

     

    I too would be interested in hearing from other 'I' serial Sheri owners about their radius. One or two have posted on the forum, are you out there?

     

    PS you can download a PDF of radius guages to print and cut out at Pickguardian.com
