hey UG,
I have a Vox Valvetronix AD100VT and when i turn up the preamp volume full i get a temporary volume increase.. e.g. when i stop playing for a couple of seconds and then play again it gets a volume increase for about 2 seconds and then goes back normal... I think this is because the tube is building up power when it is not being used... so i was wondering whether there is a way of getting rid of this temp volume increase without turning the preamp vol down
