My new Jaguar has a whole bunch of switches that repelled many a guitar player before. You know, they usually like to play without having to think about knobs or buttons. Just plug and play, and that’s okay.
But for me switches are paradise! I now have three different capacitors instead of one in my guitar, and I can even switch from foil to ceramic, if I like to, and I simply love all of the sounds they produce.
For years now I use to modify my guitars by replacing their tone capacitors by better ones. Capacitors obviously are the poor cousin of even the best manufacturers. Usually you don’t see them, and that seems to be enough of a reason to provide only the cheapest ones.
But anybody with ears to listen can hear the difference, though it’s never spectacular. With a Gibson Les Paul or the like I prefer foil caps that give a much smoother sound than the ceramic caps provided. You can turn the tone control all the way down to produce the “woman tone”. Still it will sound good and present, while ceramic caps strangle the tone until it virtually disappears!
With a Fender Guitar, they say, you should use a ceramic cap, but one that’s much bigger than the cheap ones. It is called “Orange Dime”. But the really old Strats had foil capacitors, too. After trying one of them, I would never return to a ceramic cap. But that’s a thing you can argue about.
With the Jaguar it took me some time to find out the right items, though. As always, it was trial and error, and I had to change one capacitor’s value from 0.01 uF to 0.005, for instance. The result is amazing. There is a right-in-the-face Rock sound as well as a smooth Jazz sound, and so the Jaguar has become the most versatile guitar I ever played. Oh, I forgot to tell you about the “resonance strings”: they have their own, harp-like sound adding to the many possibilities of this guitar.
