This wiring mod claiming to bypass on-board active electronics from the Guitar Electronics site caught my eye tonight ..

It doesn't mention the Clapton Mid Boost specifically .. but wouldn't it be nice Doc?

Wiring a Clapton Mid Boost gave me Fits a couple of years ago .. the connections were more complicated than a single input & output for sure ...

Any thoughts on this?

the copy:

This guitar wiring modification shows how to wire a double pole-double throw ON/ON mini switch or push/pull switch as a true bypass or active passive switch. By adding a true bypass switch allows the sound to remain pure and noise free when the preamp is not needed as we as provides an instant On/Off feature for the active electronics and allows the instrument to be used in the event the battery is dead. This wiring mod can be easily done with any active preamp or electronics including electronics from Seymour Duncan, EMG, Agular, Bartolini and many more.

the wiring diagram:

I'm absolutely no wiring guru... :wink:

But (a) anything is possible, and (b) the original Richie Sambora Signature Stratocaster MIA had a bypass switch.

Edit: Forgot about the EC Strat's volume - it's a "Control, 50k, Audio" = designed to work with the PCB only, so the above diagram won't work with the EC as is.
The Sambora model has 250K pots.
Plenty of info on both guitars in the web.

It might but I'm not sure.

The mod illustration indicates an active amplifier purely interupting the output line of the guitar. I'm not sure the Clapton mid boost is that simple.

As you note, the Clapton Mid Boost is very much tied in with the guitars wiring. It does work via a dual pot but I don't know if the overall signal path is completely down stream of the conventional controls which it would need to be if you wanted to bypass it without other strangeness occurring.

Yah!! The original wiring schematic for the pre-production Clapton Stratocaster...the one using the mode switch...can be found in A.R.Duchossoir's book, first edition. Anything else from Fender is the upgrade for the production series.

The micro switch is diagrammed in the upper right hand corner of the schematic. Regret the rotation. Suggest you print the page and enlarge it on your printer for better reading.

Yah. It's interesting though. We've been discussing this else where on Xhefri's Facebook page. The prototype guitars they sent him out the road with in '86 were pewter and red, and had 21 fret necks with. NO bypass circuit. You can see one of them on the cover/back of Duchossoir's first book and on the '86 DVD tour he did with Philinganes, Collins, and East.Image

Yet the ones they built for the '88 Winter NAMM, of which we believe mine is one of, did. The final production version went out with a 22-fret neck and no bypass.

Doc your CS pre-prod Red Clapton is so beautiful .. did I hear that you're tiring of it? ( :

and thanks for the Wiring Diagram that's a rare one .. gotta take a closer look ..

I'm about to move the "Hot Rod Brownie" on to the 'bay .. No More Wiring Changes!!

maybe another mid boost after the "EJ" build on the bench now ..

Here's the Clapton Brownie that Fender should have made .. with Mid-Boost .. P/P for Nk on & DiMarzio Area Pups that Martian recommended while refretting w/ Semi-Jumbos ..

[i][b]Been listening to the wrong dirty bird, bro.[/i][/b]

Do so. Let me know what you think!

I'm about to move the "Hot Rod Brownie" on to the 'bay .. No More Wiring Changes!!

Gee! I thought you might hang on to that one for sentimental value. But I guess YMMV. Hasn't Fender been marketing a sunburst Clapton?

Keep me updated on what you're doing with the EJ.

Best!

Doc :wink:

That guitar is a beauty fuh sure...

The diagram remains too blurry, so I can't make most of the text readable. Much of it can be guessed, but lacking especially the right lower corner parts list - and I believe 1st editions of the book are outta reach these days.
So, any chance of a clearer (part of the) pic?

I'll see what I can do. The original is not the best, and more is lost in scanning and transmitting to the computer. I'll try for a dark copy and scan that. We'll see how well that serves.

Doc :wink:

I've had good results taking a picture of printed originals .. the camera can be adjusted for better quality ..

Depending on how "shakey" I am on any given day .. may even set up the tripod ...

Syriously, the only Korea both these guys should know anything about is Huntington's Korea. :oops:
