Every time I now rebuild one of my guitars the first things that I order are a pair of Bumblebees for the job. The only guitar in my collection that doesn't have them is my soon to be finished SG, but that's running silly SD pickups for that added punch, and is more of a silly toy rather than a working guitar.
Just hunt down some of the dedicated audio sites on the web and you'll run into a lot of the audio-philes who swear by paper and oil capacitors (Bumblebee and the likes) for their audio equipment, so it's not just us guitarists who love 'em.
My Orville has just literally yesterday had it's new Stormy Mondays wired into place with CTS pots, Switchcraft switch, vintage braided cable and one pair of bumblebees and it sounds amazing!
