I've just got back my 2003 Tele (can't recall if they were American Series or Standard then) after some upgrades by my favourite luthier. He does top quality work and is very reasonably priced. It went in for fret dressing to smooth out some minor hollow spots, replacement of a crackling volume pot and the fitting of a Callaham bridge with the three compensated brass saddles. I'd been thinking about some hotter pickups too, but was persuaded to wait a while, partly on FDP advice. I thought I should at least check if the new bridge adds any sustain. When I picked the guitar up, the tech also suggested a treble bleed mod and he did it for me there and then, in a few minutes, at no extra cost. It would have taken me all day.

This is the only electric guitar I've ever kept for a lot of years. I've always liked it, but like it even more now. The Callaham bridge has definitely added sustain and the sound is maybe a bit brighter, though the treble bleed mod might be confusing that as I normally play with the volume set a couple of notches below max. I certainly needed to adjust my basic amp settings to cut some treble. Re hotter pickups, I now think there's no need. So far.

Very cool.

Nothing like a trip to the beauty salon to make one feel all primped & pretty.

I'd be curious what he used for the treble bleed. I know many Tele schematics show a .001uF cap across the volume control, but I've found that big a cap to be too extreme. As you turn down the volume, too much of the treble remains and the tone is inconsistent.

If I use a cap only, I'll start with a 200pF or 250pF and adjust to taste. I've used as low as 100pF and as high as 470pF. I've tried combinations of resistors and caps in parallel, and a resistor and cap in series. I prefer in series. The same values are used in either case.

A passive circuit like a passive volume with a treble bleed will sound diffferent depending on the impedance the guitar is plugged into. Most amps and effects have 1meg ohm input impedance. Some are around 500k ohms, which is OK. Some effects and some inputs in amps and mixers are much lower, such as an unbuffered Cry Baby, some fuzzes, many older effects and amps, and most "high" impedance inputs on mixers. These will run around 50k, which is too low and will load down a guitar pickup, reducing clarity and volume. Into low impedances the bright cap will sound different than into proper high impedance.

Steve - the tech happened to mention the best treble bleed he'd ever found (and he's been in business 20 years) is the one used by Suhr. I just found this on a Suhr forum from their Director of Production no less: "We use a 150k resistor in parallel with a 680pf capacitor on the volume pot between the input and the wiper".
