Hi George,

I also noticed that the schematic gives the impression the transformer is incorporated into selector. There are variable transformers available so it's possible Gibson did that.

As I expected your measurements indicate the extra windings needed to match high impedance added extra resistance, so something is definitely not right.

I have wondered if the guitar electronics had been modified. But I admit I am leary of taking everything out. Mainly because of friend of mine warned me about taking the electronics out of a 1960's Silvertone/Harmony guitar and the nightmare getting it all back in through the f holes. If I go that far I will probably hire someone to take care of it.

By the way. Saw the pictures of your low impedance collection. Very nice.

Thanks for taking time to get the resistance values. That helps a lot.

Hi Walter,

You might be able to get a better look by taking the bridge pickup out, that should give you a larger opening to see through & take things out if it comes to that. I think the block of wood in the center of the guitar is routed out on the control side, but not 100% sure. Getting the pots and jacks out & back in can be tricky. Some people tie string around the posts, I've had luck using the right size shrink tubing, pushed on the knurl post after the knob is removed. It grips tight, pulls the pot back in straight & you can slip the nut & washer on over the shrink tubing.

Good luck,
George

Hi George,

Your measurements definitely point to something odd in the wiring of my guitar.

I took measurements with a 15' Hosa balanced low impedance cable. I only get readings across pins 1 and 2, not 2 and 3 as yours is. My readings are 13.9 ohms and I get the same reading no matter what the level settings are at.

Another thing odd is using the same balanced cable through my Behringer mixing board seems to work (I get volume).

Not sure if I will tackle this further or bring it to an authorized repair person to have it looked at. I am retired so I obviously have the time just not sure if I won't the frustration.

Your ideas to fish things back through make sense though and I have watched several videos of how to put things back in so I may give it a try.

Thanks for you help,

Walter

Hi Walter,

Most authorized repair people likely have never seen one of these, few would know how to fix one (other than techniques to getting things apart & back together). I'm no expert by a long shot either. It almost sounds like something might be shorting out some contacts on your Level Control switch. It might have came loose & was retightened 180 degrees or so from where it was intended to be. Maybe you could just loosen it & try turning it gently & see if it works............ Might be a bare ground wire causing the trouble.

I've found a site called "Woody's" on the net (maybe You did, Grog recommended it?). There are many people with such instruments. Even found a guitar stamped on the very same day as mine. http://www.rlinwood..../LPR_Master.htm

Hi George and everyone.

I put my Les Paul Signature into Ron Pace Guitar Repair in Houston. I gave Ron a copy of the schematic and he is working hard to get the wiring corrected but is having difficulties.

He discovered the guitar had been rewired as I suspected. One thing he noticed was there was no stereo jack, both were standard. There was a broken cap also.

Has anyone that owns one of these ever went through the wiring or taken pictures of the wiring with a camera? Ron said the wiring is tricky and he was wondering if anyone has done this before to help point him in the correct direction.

Thanks,

Walter

Hi Walter,

I did work on part of one about 15 years ago. I just remember it taking me a month to get up the nerve to disassemble the few things I had to take apart to fix it. I have no photos, but I do have a parts list. It does have a few values, many things are Gibson Part #'s which is of little help...........

Hope this might help find something,
George

Hi George,

Thanks for the information. I chatted with Ron. He found a replacement for the rotary phase pot. He is still working through the wiring but feels he can figure it out.

I will post again when the work gets completed.

Hello everyone,

I have a request from Ron Pace. He wanted to know if someone could take picture of their LP Signature wiring.

Using either a mirror or snake camera. Or if someone in the Houston area has a LP Signature I happen to have a snake camera and could take the pictures myself.

Thanks,

Walter

Hi Walter,
Checking out a local vintage dealer's webpage, I ran into this......
http://www.williesgu.../3/inventory/22
It looks like they had to rewire it like a normal Les Paul & knowing Nate, he kept the remaining original parts with it.
He may have what your looking for out of the guitar if it hadn't been totally butchered up by it's previous owner. They might be willing to photograph it.
Might be worth a shot to have Ron talk to whoever did the work on it, even though they were unable to bring it back to original specs.

Hello!

Does any of You have a dysfunctional low-Z pickup in perfect aesthetical condition for sale?

I would like to replace the plastic cover of the bridge pickup on my Recording as it has some scratches.

Well, seems to be an impossible quest. Anyways, I thought I would ask.

Thank You!

Best wishes... Bence

Hi Bence,
This eBay seller had these that they were selling as build kits with a red plastic bobbin. They sold many NOS Gibson items from the Kalamazoo plant. It is possible that they were for the Triumph Bass, but I believe it was for the guitar. It's hard to say if they have any more laying around.
http://stores.ebay.com/greatdealz1967/
Also, Gibson made them again for the Les Paul Recording II (Iridium). They look like an exact match. You can see if Gibson could sell you a couple.............
Good Luck,
George

Thank You, George!

Unfortunately, this eBay seller seems to be out of business. :(

Thanks for the information George. I sent an email request to them to see if something is available.

I bought a Wifi Borescope. It's sort of awkward, but I made an attempt to take some photos of the Impedance Level switch on the Les Paul Signature guitar.

Hello!

Browsing through the Sam Ash pages, I've found an L5-S with low-impedance pickups. It's in New York City, if someone is interested:
