Best Tone Capacitor for bass top end?

[quote name='Bo Millward' post='918961' date='Aug 8 2010, 07:14 PM']Any suggestions on what kind of tone caps are best for bass? Which would give me the most clarity and high frequency out-put?

Cheers

Metallised Polyester or Polypropylene, as for value it depends on the circuit design.

Mr Foxen is correct in a slightly cheeky way, - clear high frequency output is was a capacitor doesn't do, it rolls off the trebles as the tone pot is turned down, it is a high pass filter. Most high freq response is of course with the tone on 10, thats zero(ish) resistance and the cap is not in play.
Can we direct you to this fascinating recent post which explores many aspects of the cap arguments?

My summary would be that it takes sensitive electronic measuring equipment to differentiate the tonal differences between cap types, and negligible effect for a pair of ears to be able to tell the difference.

Most basses have the tone control wired as a series RC connected in parallel across the output. With the tone control at 10 the resistance will be at the maximum value (not minimum) to minimize the HF current through the cap.

Haha! Why didn't I think of that it's cool guys i'll just f*** off my tone pot and wire my bass up with a volume for each pick-up then a master volume for the full circuit. Cheers for the help peeps!
