So, I'm stationed on a 25 year old US Navy ship, but most of the equipment on board it was designed and built closer to 30-40 years ago. Some of it has been upgraded, yes, but the majority of it is ancient, analog equipment. (It probably comes as no surprise to any of you yanks, but your tax money goes to politicians pockets, not force modernization) Anyway, one of the ship's 2M techs (2M is what we call it when you repair stuff by taking it apart and resoldering it back together again at the component level. Nearly a lost art in todays navy) is also a bass player, and he has been teaching me how to do some basic electronics work while we're on deployment. I have my P-bass and my Tele (both MIM) on board, and he has looked over my shoulder while I take stuff apart and put it back together again. Recently, while cleaning out some old boxes of junk to throw it out, we found a stash of old (like ... old) caps. Among them, there were some .022uF and .1uF. (there were other in the "guitar" use range, but unfortunately no .047uF among them) So we're thinking that we should probably do some experimenting and see if we can't find some nice sounds or random lightening in a bottle. They were bound for the garbage anyway, and if we DO find something cool, then it'll be just about impossible to replicate. So I was wondering if anyone else has done this kind of thing - just pulled random electronics off of old non-guitar related devices and had any luck?
