[ES-347 2 way switch]

Hello everyone,

I am a tech and I recently had a customer bring a Gibson ES-347 with the 2way toggle switch that coil taps the p/u's.

His switch sticks whenever in the down position (coil tapping the p/u's) and is insanely hard to get it back. Almost to the point of forcing the switch. He and I are wondering if it's possible to get these switches still, or if this is a common problem where a quick fix is only needed. I don't have the year on the guitar and I didn't really get a great look at it since the customer was in a hurry but any help would be greatly appreciated.

 

 

Thanks,

Aaron

 

 

Hi, have you found those? I'm looking for one too.

 

Thanks!

The coil-tap switch is simply wired by connecting the single-coil "hot" wire of each pickup to one side of the switch, and the ground wire (braided shield) to the other side of the switch. When the switch is in the "on" position it connects the two wires of the pickup together. This creates what is known as a "dead short", meaning the signal from that coil is diverted directly to ground, not allowing the signal to pass any further downstream.

 

Hi. Thanks for that. Is it possible to use a standard 3 way switch to do that? I would like to use the hole I already have and move the pickup selector to another spot. So I cannot use a mini-toggle.

 

Or will any of these work?

Thanks a lot.

Thanks for this. I just need to figure out how the DPST is wired then. Do you know how that is done? thanks.

 

 

 

Here's what the schematic is showing:

 

The double coil lead from both pickups wires to vol - tone - switch - jack in standard fashion of most double pickup guitars. The audio signal travels down this wire at all times and all modes.

 

The single coil lead for each pickup wires to a DPST (double pole, single throw) on/off switch which when engaged, dead shorts the single coil of each pickup to ground. Therefore removing that coil from the (above) signal path.

 

So the pickup lead from the single coil is being used only as a "shorting wire", and at no time is passing audio. The audio signal travels down the other wire at all times.

 

Stated a little differently: The coil tap switch does not switch the path of the audio, it just removes a coil from the path.

Hello,

 

I am trying to rewire a pair of Gibson Dirty Fingers humbuckers that I had in my ES-347 and drop them in a 335 copy I have.

 

The problem is, I can't understand the schematics i found on the Gibson website: http://www.gibson.com/Files/schematics/ES347wCoilTap.PDF

 

Does anyone have an illustrated diagram for this?

 

As the pickups have 2 braided wires, one for HB and one for SC, I assume, it gets even more difficult for me.

 

Thank you!

Sorry I have no audio; but I have some pics:

 

The serial # is 90510625' date=' suggesting 1990 as the production year. No metal nut or pickup selector on one of the upper bouts of the guitar, as on earlier models. I once thought to change the pickups to '57 PAF's, but those pickups are 2-wire leads and would disable the coil-tap. A coil tap needs a 4 wire lead from the pu. I like the dirty fingers pu because it is not a ceramic type, but rivals the original 57 PAF's with more windings. Please correct me if I'm wrong. I love the sound driven or tuned to a jazzbox sound; it's a versatile guitar. Though similar to a BB King model (sans Varitone) in hardware, I think the dirty fingers sound better than the 490(?) pickups. I even like the TP-6 tailpiece, as it is a functional part in fine tuning the guitar.[/quote']

 

The Dirty Fingers are ceramic, as far as I know (Sweetwater)

 

And you actually need only 3 wires. That's what I ordered from Lindy Fralin and it worked just fine.

Hi zojo, this might be the answer for your tremolo desire without affecting the guitar:

Steve-What a way to start the new year. Sorry man. Hope insurance paid ya what it was worth. I bought my 347 in 1980 but think it's a '79. S/N 70119009. Can anyone confirm this? Yea mine has brass nut. Had some problems with coil tap switch but otherwise it practically plays itself. I've heard and read it wasn't a big seller is probably why it's hard to find info on 'em. Love to add a tremlo to mine and sure that'll affect value but hell I'll probably die with it anyways. Beautiful guitars you guys posted!

Mine is a 82 Tobacco burst. According to the Blue Book, they were manufactured from '78 to '91.
