Hey all,
i searched for this, but oddly enough, this hasn't come up in this case...

I'm building a Fuzz Face clone, from the vero of the 1969 Boutique version. Anyway, the pots in it are 500k value pots, which bitsbox dont stock. Similarly, the trimmer is a 10k, which bitsbox also don't have.

Could i use a 470k Pot (its for Volume) instead, and a 10k POT instead of the trimmer?
thanks

Bitsbox do have a 10k trimmer http://www.bitsbox.co.uk/resistors/presets.html although an external 10k pot would work as a biasing pot.

And yea 470k should be fine, for some reason in the U.K 4.7, 47,470 is more common than 5.0, 50, 500 which are more common in the U.S.

The original just used parts they had lying about or could easily get anyway so don't worry about being too true.
