I have s 2007 American Elite Stratocaster HSS Shawbucker. The Fender site says all American series guitars have the treble bleed circuit from the factory.<br /> <br /> I clearly have treble bleed on mine, guessing that it was built before that mod was incorporated. It does have the switch on the volume pot that kills all tone pot settings.<br /> <br /> I don't know what the value is on my volume pot. Has anyone else encountered this & if so, what value cap & resistor did you use?<br /> <br /> Thank you!

Assuming you mean "American Deluxe" and not "American Elite" as the "American Elite" came out just a year ago or so. There is (I think) no such thing as a "2007 American Elite."<br /> <br /> If it IS an "American Deluxe", then that switch on the volume pot does not "kill all the tone pot settings" at all (unless somebody modified that guitar). In factory wiring, that "S-1" switch re-configures the wiring of the pickups (when engaged) from parallel p/up wiring to a variety of series p/up wiring schemes.<br /> <br /> You might still be able to twist up a cap and resistor to wire across the volume-pot lugs (input and wiper). You might need to experiment with the cap and resistor values.<br /> <br /> If you can find room on the volume pot lugs, start with a 150K-ohm 1/4-watt resistor and twist it up in parallel with a .001uF capacitor. Clip each of the twisted legs to the input and the wiper of your volume pot.

Set the volume pot to 10. Set your meter to read Ohms. Measure across the two outer legs on the volume pot. That will tell you the value of the volume pot.

JJuran - Thank you very much. You are correct; it is a Deluxe. Was just looking at an Elite; must have still been on my mind!<br /> <br /> I read an old Fender ad for my guitar some time back and they didn't call it a S1 switch, it was described as one that kills the tone settings. Doing more research today, I did confirm it was as you described as well. <br /> <br /> Thank you also for the suggestions for the treble bleed components.<br />

Peegoo - thank you for the process on how to check my volume pot.

Peegoo: If you set the Vol to 10, aren't you measuring the Vol pot in parallel with whatever pickups are selected?<br /> If so, you are going to get a very low reading.<br /> <br /> Unless I'm missing something.......<br />

Dino: I'm not clear about your original post.<br /> Does your guitar have the treble bleed mod installed?<br /> Or does it not have it, and you'd like to know what values may work without too much experimentation?<br /> I only looked at two schematics in the attached link.<br /> Both of them had an RC parallel treble bleed shown.<br /> <br /> Also, was there a "Shawbucker" in 2007? I thought that this was a relatively new term/type of pickup.<br /> <br /> Have you tried actually looking at the pots? You might be able to see the value(s), either on the bottom or the side.<br /> <br /> In any case, if you follow the attached link you may be able to find out what you actually have and/or want.<br />

Thanks ejm for that link to the wiring diagrams. From there I count no less than 7 different American Deluxe HSS stratocasters. Some have treble bleed circuits on them, some don't. Some use 1M volume pots, some use 250K pots. <br /> <br /> Dino - have a look at the link that ejm posted and decide for yourself which of those guitars is yours and whether it has the treble bleed mod or not. And also which value your volume pot is (assuming the guitar is not modified).<br /> <br />

While the pickguard is off to measure the volume pot (the value may well be written on it), have a careful look at the pot. If there is a capacitor and probably a resistor between the hot and middle lugs, it has a treble bleed.

"...If you set the Vol to 10, aren't you measuring the Vol pot in parallel with whatever pickups are selected?..."<br /> <br /> That's correct. You can't really measure the volume pot's value in circuit. Need to unsolder something.<br /> <br /> The suggested method is actually a good way to measure a pickup's DC resistance.
