Не, lart , не убедил. 

Looking inside my brand new ES 339 with the Memphis Tone circuit, I see on both volume pots, one small cap that is about the size of a baby aspirin and is dull orange in color. Just an FYI for all concerned.

This kit consists of a capacitor and a resistor, which are wired in parallel across two of the lugs on the volume pot in order to prevent treble loss as the volume control is rolled down. The values are 680pF/220K (single coils) and 1000pF/220K (humbuckers). There is nothing special about these components, you can buy them from Radio Shack for 50 cents or less (we're guessing). We charge $2.60 because of the time it takes to order them, receive them into inventory, twist the leads together and cut to length, print labels, print/cut/fold instruction diagrams, and package the resulting kits/diagrams into little zip lock bags and label them. So you're not paying for the parts here, you're paying for the time it takes us to package them and the convenience of not having to track down the parts yourself.

We're telling you this so you don't think we're trying to rip you off. With the cost of gas being what it is (not to mention the value of your time), it's surely cheaper to purchase one of these from us and save your time and gas. On the other hand, if you want a dozen of them, it might be worth your while to stop by Radio Shack or similar and buy the components there, you'll definitely save a few bucks.
