treble pot

What difference in tone does a 1m treble pot have over a 250k?

1M has more treble, but the amp seems to scream more with the 1M value, even when it's turned down quite a lot.

[bigsmitty]

does that mean it also has more gain?

Not really - it just means it's losing less signal between stages. The gain is the gain... set by resistor/cap values at the tube itself. The whole tone control network is a big 'loss' circuit. Change the component values, you change what's being (intentionally) lost. The tone controls produce no gain of their own.

Gotcha, Thanks dudes!

My preference is for 250k L. No question.

http://www.duncanamps.com/tsc/ will show you the difference. Just throw in the 1M and 250K value and compare the frequency curves.
