If I were you, I'd buy a number of cheaper caps to experiment with the values before getting anything more expensive like Hovlands or 'Vitamin Q' caps. There've been several debates about this at the Duncan forum - trying to decide if expensive caps make a real difference, I mean technically, in the tone circuit of a guitar, or if it's more of a psychological effect due to the reputation and high price of the Hovlands and such. All the positive reviews were convincing but then one of the 'pickup gurus' there did a real side-by-side comparison (the only one I know of so far) using a Hovland and an Orange Drop wired to a push-pull pot so that the two caps could be compared at any tone control setting. Guess what he found - he couldn't hear a difference. Knowing that his ears are way better than mine, experiencing with orange drops yielded good enough results for me. At the end of the day, though, the only thing that matters is if you personally perceive a difference - if you like the sound more with a more expensive cap, it was worth indeed. 8)
