1meg/500K

[geoff 1965]

hello,
need some help or rather confirmation here guys,i've been browsing through the old posts and came across something one of the amp tech's said quote "a 500K pot will yield slightly less gain than a 1meg pot"
is this true? i would have thought the lower resistance 500K would give you a bit more gain?

The resistance in a volume pot is acting as a voltage divider (not as a rheostat) -- at full volume all of the pot's resistance is between the signal and ground, preventing the signal from "leaking out". So a higher resistance pot keeps more signal in the amplification chain.

aha! i've known the pot is a variable voltage divider "but" i have'nt seen it in that perspective,that makes sense and helps a lot.
thank you
