J,

Did you use the High Pass circuit? I keep hearing conflicting stories about how this wiring schematic works. There are only so many ways to wire up pots. My guess is that the high pass circuit is what does the trick.

LM
The pic of the cavity shows the extra resistor installed on the neck volume pot. I had my LP Pro wired up this way with the RS kit and almost immediately had it removed. I didn't like the high-pass at all. In fact, i like the '50s wiring scheme better than the RS wiring scheme. Personal preference, but that's what the tone hunt is all about :D
 
Re: Results from my LP mods (pics)

I didn't catch the resistor on the neck volume pot the first time I looked.

That guitar is wired pickups to #3, switch #2 and #1 grounded just like current production LPs. The only thing thats different (short of the components and the added resistor) is that the caps are connected to the grounded posts (#1) of the volume pots. I have never seen a cap wired to that terminal in any other guitar, ever and I've seen quite a few guitars and quite a few schematics.

I didn't think that you'd get signal at a grounded terminal, but I may be wrong.

Nice guitar Bro.
 
Re: Results from my LP mods (pics)

OK I went to my luthier to discuss the problem and he told me they did NOT remove the anchors that are in the wood and that they just changed out the bolts/studs and the tail piece. He then showed me other LPs that had the same missing finish so he didn't do it. I never saw it because my tail covered it. I would be intrested to hear if anyone else has the missing finish so you guys with pauls go look at where your studs screw into the body and see if there is finish all the way up to the stud or if there is a ring of bare wood (please).

GJ - I went and set both tailpieces side by side and there is hardly any difference at all. The only difference is one has oxidation and scratches from for months of playing where the new one is nice and clean.

xerxes - I sold all my recording equipment so no clips in the immediate future.

Now do I understand this correctly?... Is it only necessary to replace the tailpiece? Are the tailpc. studs aluminum? Is the bridge aluminum as well? I'm a little uncertain as to what's being changed over here. Help anyone?


The only thing that was changed were the studs that screw into the anchors and the tail piece. I dont have any problems with the bridge so I just left it stock.

Nice guitar Bro.

All the Fender Telecaster wiring diagrams over at MrGearhead show the capacitor grounded to terminal 1 of the Volume pot instead of at the Tone pot shell. I would assume the result would be the same, since both points are used as ground.

In the case of grounding to the Volume pot's terminal 1, I suppose then one wouldn't have to jumper ground the Tone pot's shell, since it wouldn't be used to ground the cap. But in the case of the Tele, I think the control plate already grounds the Tone pot shell...

Jay,
I've been trying to say this for over a month now (since I modded mine) switching from the Nashville Tune-o-matic to an ABR-1 bridge improves the tone substantially more than changing the tailpiece. I've done both mods on my '01 Standard and I could hardly notice the change from swapping the tailpiece. On the other hand, the difference between the two bridges was like night and day. You can get adapter bushings to convert from a Nashville TOM to a Gibson ABR-1 from Kenny at Solid Body Guitar (www.solidbodyguitar.com) or from Stew Mac.
 
Re: Results from my LP mods (pics)

In the ABR-1...is there a tonal difference between chrome and nickel, or is it purely cosmetic?

All of the Gibsons I have seen have this bare wood section, I feel it looks a bit nasty, something I wish gibson would rectify. I guess there must be a reason for it though.

Thanks for the heads up...
 
Re: Results from my LP mods (pics)

I couldn't tell a tonal difference between the two ABR bridges. I would ask Kenny as he's an even more anal tone-nazi than I am.
 
Re: Results from my LP mods (pics)

The RS upgrade kit is the single best $50 you can spend on your LP, in my opinion. I have in both of mine now and couldn't be happier (haven't got it in my 77 GT, still wondering about leaving it stock...). As the first poster said, usability of the neck pup and the volume and tone controls increase dramatically...

For $50 it is a no-brainer...

Bob: Yes, they replaced the poles. Man am I glad you said something. I didnt even check to see if when they removed the poles if finish came with it. Check out the pic :grumble: back to the luthier....

The pic's a bit blurry, but it looks as though the finish came off where it was applied over the stud anchors. That's not unusual, as the paint doesn't stick to metal like it does wood. Removing the anchors or just unscrewing the lugs will sometimes lift that ring of finish off the anchor. If that's what we're looking at, it's a normal occurance and I wouldn't give your tech any grief over it.
 
Re: Results from my LP mods (pics)

So im a little confused whate xactly does the RS kit do? Is it just the tail piece? for a lighter wieght? I dunno man id be idna ticked aboutt he finsih especially cuz its a 3000$ and up guitar he just nicked. He should have at least told you about it. Common courtisy and professional like.
 
Re: Results from my LP mods (pics)

Anyone want information on the RS kit, review, discussions etc, go to the Les Paul Forum - we've been debating it there for months...
 
Re: Results from my LP mods (pics)

Okie dokie, I looked at some old Tele schematics and I see whats going on now. The feed line from the volume pots is obscured by the cap for the most part and thats the part I was missing.

Cool.

The RS kit is strictly a wiring, pot and cap upgrade.

After researching the finish issue I have found it is common occurance and my luthier didn't do it.


Duncan, the LPF is where I got all the ideas for the mods. I lurk there daily and post on occasion. Great resource for LP owners/fans.
