Re: jb jazz for an oscar schmidt semi hollow?
ok so the jb might need some knob tweaking to sound good but would split nicely and the 59 would not split nicely or sound as good split but might be a better match off the bat in a semi hollow. I don't see the vintage blues set on the gc site (I do see it elsewhere) I may see if they will simply match those prices and let my bud return the jb/jazz.
so I have concluded I think he would be better off with a 59 bridge...that leaves the neck...
jazz or 59 matched with a 59 bridge in all probability. I know the jazz is known to be fairly articulate...would the 59 neck sound muddy again in a 335 copy?
The JazzN is a great neck PU, not quite as boomy on the bass as a '59N; I use both PU's myself, but I like plenty of low end (not everyone does). Both of these are 1950's PAF type's with A5 magnets, which give good treble & clarity.
For splitting, you need 4 conductor wires (plus ground). If you have the single lead (plus ground) you can't access both coils to shut one off. Just about any HB splits well in the neck, as that position is loud & warm (ample string vibration). In the neck, a low ohm HB will usually be bright to begin with, and very bright split. Maybe you'll need to dial down the tone control. One thing that helps is in coil cut to keep the bridge's slug coil on rather than the screw coil (a little more warmth & volume). For example, one coil of a JB has about 8,000 ohms, which is just about what both coils of a '59B have combined. Everything else being equal, as you add windings to a coil, it will gradually increase the resistance (ohms), add volume & midrange, and reduce the treble & clarity. Extra windings are good for a bridge PU, but not necessarily for a neck. But different PU's are wound differently. The thinner wire gauge and narrow coils in a JB help give it that distinctive ice pick sound in spite of the extra windings.
A '59 pair or a '59B/JazzN combo are very good combinations, and work well for many players on this forum. You won't hear many guys complaining about them. Nice cleans & very good with overdrive. These have a higher success rate than a JB. All I'm trying to do is increase your odds of getting it right on the first shot, especially if you're paying a tech.
