Hi everybody!

I hope someone can kindly help me.

I removed the pickguard with the electronics of my 2006 Clapton to install a new one: I just dissoldered the connections to jack (3 wires), to trem claw (1 wire) e unscrewed the wire to cavity.

Now, I tried to install again the old assembly: I did the soldering as it was before and I checked it with the schematics I downloaded.

But surprisingly there is a problem: the more I turn clockwise the booster pot (to 10), the less boost I get, the more I turn it counterclockwise (to 1), the more boost I have.

Could please anybody tell me why? :-(

Thank you so much in advance!

Steve.

i may be wrong

So at what point does the boost peak. You didnt wire it to the TBX pot did you? I can get my mits on my colourcoded schematic later in the week.

Is your 9V on line? The boost will do that when the battery is low.

Thanks to all of you!

Actually I did not touch the solderings among pots, pickups and switch: I only dissoldered those to jack and to trem claw.

The boost peaks at 1 and not at 10. I edited my mistake, sorry!

I just installed a new battery: no changes...:-(
however I am grateful to you for your efforts!

Steve

ps. Should I email Fender? To which address please?.

All i can guess is that the booster pot or tbx are wired icorrectly and that they need checking out. Ok heres what i used along with the fender schematic

http://areyouexperienced.net/fender_clapton_mid_boost_kit.htm

use that in congunction with the fender schematic

http://www.fender.com/support/diagrams/pdf_temp1/stratocaster/0107602B/SD0107602BPg2.pdf

NOTE THE TBX POT ON THE FENDER SCHEMATIC IS IN THE MIDDLE SLOT. ON THE PREVIOUS LINK ITS IN THE BOTTOM SLOT.

Heres a link to a good TBX mod that improves its control. Originaly posted on another site by someone called Doc :?: :?: :?:
http://www.blueguitar.org/new/schem/_gtr/tbx-mods_and_details.pdf


All i can reccomend is that you use the above links to check your wiring out. Theres a lot of wires on that boost circuit.

Good luck!

swap the wires on the jackplug around. it sounds like you may have them reversed or the negative from the battery in the wrong place.

This may be totally dumb but, I've been dumb before.
I'm a lefty and I have had a lefty Strat with a righty pot in it. Could you have a lefty pot in your (I asume) righty Strat?
Again, I'm a lefty, I think backwards.

Love,
Todd

Haha! I've always wondered privately about that. It nearly got answered on a thread here several months ago - but not quite. I don't remember ever seeing Fender type knobs with the numbers going in the other direction; that may be your biggest problem, unless someone knows a source for them.

If I'm understanding my pots correctly (and I may not be) then reversing the wiring on the tags should make the pot work in reverse, at least for an ordinary type tone/volume pot. ...Is that right?

And now I've said it out loud, if I am after all wrong someone here will shoot me down in flames and we will get the correct answer.

To the OP: if the output jack wires are the only part of the soldering you've touched, then that you have put them back the wrong way around can be the only answer - no? Quick enough to open up the jack and switch those wires over to check, at any rate.

"Eliminate the impossible and what you are left with is the solution, no matter how improbable." Who said that...? Where's my deer-stalker?

Cheers - C

When playing my guitar and looking down, if my volume is on 1 and I want to get louder (and who doesn't?), I touch my (left) pinky to the left side of the knob and push down - turning it clockwise as it rolls up my pinky.
This works for my 2x'77Strats, my 2005 Delux strat, and my '95 Standard Tele.
Oddly, my '74ish J-Bass (sn#407512) goes the other way.

Love,
Todd

Reversed pot seems to be the answer mate.

Hmm, interesting. I have a (right-handed) '75 Reissue Jazz Bass and the volume knobs get louder as they are turned clockwise - just the same as my (right-handed) Strats.

Itching to hear from someone who knows for sure whether it is indeed just a matter of which way round the tags are wired on the pots.

The only real reason I can think of that any of this matters for a left-hander is precisely the issue you hint at, that of producing volume swells with the pinky hooked around the knob. To me that is a particularly valuable part of the layout of a Strat; the convenient placing of that volume knob. If it worked the other way around in relation to the picking hand - well, you could still do it, but it wouldn't be so easy... I think.

Any left-handers with views on that?

Cheers - C
