Cap sizes /quality

[ourclarioncall]

Just looking at the idea of having a cap switch . 

I would be using a DPDT on-on-on

Im thinking that if in the future I go ahead and try this then which type of caps should I use

i would be needing two caps on a DPDT on-on-on. Actually, I will need three switches, one for each pickup , so that will be 6 caps. Space will be tight 

the only ones I’ve used are the big sprague orange drop ones which cost Approx £2 to £6 each, but I also have some Mylar polyester film (small green ones) that are a lot more flimsy. They are £1.39 for a pack of ten 

I think I read the opinion is that it doesn’t matter too much which cap you use , they all pretty much do the same thing. I wouldn’t know

but basically, I would like caps that are smaller, and cheaper is always a bonus

occ,


You really should start brushing up on your Search-Fu. Although I have a head start on you, still and all, the Search function returned this result, which exactly answers your question..... about 11-1/2 years ago! Go here: Free Woman Tone

Adjust cap values to taste, of course.


As to the "quality" of capacitors in general, and particularly as suited for guitars, try this posting: ChrisK's thoughts on capacitors

i thought I’d impress you with a bit of research/ info I dug up via google months back , but now realised it was about resistors not caps . Oh well, here it is anyway ...

RESISTORS

Thick film
Thin film (= metal film)
Carbon (hard to find)
Wire wound power
Wire wound precision (expensive)
Metal foil (very expensive)

VISHAY have acquired most of the high quality resistor brands such as Beyschlag, Dale ,Draloric, Roederstein, sprague

VISHAY also have their own manufactured and invented the metal foil technology

small signal-wise (guitars, stompboxes, even the majority of solid state amp sections) it matters very little with resistor choice (at this point 1/4w metal films are about the same price as carbon films)
for higher voltage stuff (think tube amps) resistor composition is a whole bag of worms that others have covered elsewhere. besides composition there's power ratings to think about, as lower noise can be expected from an overrated resistor. i try to use 2w metal oxide resistors in most spots besides input grid resistors (I'll use metal film there) and of course screen resistors (where 5w rating is better it's much cheaper to use cement resistors). but i do have a ton of salvaged carbon comp resistors that is they test within tolerance i may use. they certainly look cool
