Changing Electrolytic Capacitors to Film Capacitors Boss DS1

If you have read & researched Boss DS1 mods you will find that a lot of people will state that swapping the electrolytic capacitors for non polarized film capacitors will help with giving the pedal a more Hi-Fi sound.

This got me thinking & got me to the electronics store, i got some quality film capacitors to replace the electrolytic's in the pedal to see if it would make a difference. with the electrolytic cap's in the pedal they have a tolerance of +/- 20% & the film caps i got have a tolerance of +/- 5%. thats a huge difference and so obviously the results of replacing as many electro's to films would make some audible difference, but how much? Seeming i was on a mission to make my DS1 sound more "HiFi" i also replaced the stock film caps with new film caps that have a tighter tolerance, with the stock film caps having a +/- 10% tolerance the new film cap's +/- 5% tolerance & higher quality could make a little difference.

i got to work with replacing the capacitors and in the end i really couldn't hear any difference at all IMHO, maybe my ears aren't as good as the Pro's but the difference wasn't that much if any. I also believe that the subtle difference in tone was because if the tolerance of the film caps. they have a much tighter tolerance and that means that the values of each cap would be slightly different from the original electrolytic capacitors which = a slightly different circuit for a bit of a different tone.

i kept the film caps in the pedal because i spent money on them and they dont make the pedal sound any worse, but in the end its not really worth the trouble of replacing.
