Unorthodox wiring diagram...or is it?

[cowpunk]

I hope it's cool to start a new thread about this subject. I figured it was far enough off the subject of my previous post @ http://www.tdpri.com/forum/tele-tech...ncan-pups.html to warrant a new thread.

I am looking at whether or not I should rewire (or have rewired as I'm starting to realize my soldering skills may not be up to the task) my Lite Ash Tele. When it was modded for treble bleed the tech did what you see in the pic below.

I can't seem to find anything online that promotes this as a proper wiring scheme. I'm just wondering if anybody's seen this? What might be the effect of the tone cap placement?

Looks good, tone cap is wired like Gibson does it and by having it on the middle volume terminal is the 50's mod (Fezz Parka). High pass filter (.001) on the volume pot is a common thing too.

Look up the Fezz Parka mod to see what that does, and having the tone pot wired like it is doesn't make any difference vs. how Fender does it (grounding the cap).

What are you trying to achieve? Presumably you want to get rid of the hideous treble bleed?

[sjtalon]

I forgot to mention it is funny he put a high pass on there as with the 50's mod you shouldn't have as much of a problem in that regard.

Funny. I tried removing the treble bleed and it made the guitar sound thinner. The exact opposite of what I assumed would happen. When I would tie it back in, the tone thickened back up. That's why I assumed there was something screwy with the wiring scheme. I thought maybe wiring the cap to the output of the volume pot instead of shunting the treble to ground may have something to do with this. Maybe the combination of the treble bleed and gibson 50s wiring is causing this counter-intuitive interaction?

The treble bleed didn't bother me in the guitar's stock wiring. Here's the original wiring diagram:

Did it again sjtalon. I didn't read your post carefully enough. So basically this shouldn't sound much different than the stock wiring, save the Fezz Parka wiring? I wonder if that's (Fezz) what I'm not digging. For some reason the Fezz Parka mod it sounds fuller and punchier with the treble bleed in conjunction. I'm a little less lost, but I wonder what difference the TB cap really makes? I'm thinking of tracking down the tech that did this. Maybe he knows something we don't.

Right, FP should be noticeable.

For kicks, you could take the cap off the middle vol. pot and put it on the terminal with the switch wire (that would make it standard). With a test lead you could play with it back and forth there.

So you have a double whammy going on, TB and FP vs. a standard scheme.

As far as things being strange with taking the TB off for you is the pot me be bad, or need a cleaning....spray it out with contact cleaner (tone too).

Do you have a multi-meter ? Test the vol . pot through it's sweep. It should be pretty close to 250K when @ 10.

I will look into all those things. I'll probably just replace the pots-start with a clean slate. They're both CTS 250Ks, but they've been around a while. I liked the original wiring (tone wired to the input terminal of the volume pot) so I may end up going back to that after all. Again, I've learned a lot. Thanks for your help.
