Also to add, is to turn tube amps on let the tubes get warm(few minutes) and then hit the stanby switch(if you have one ) if your not ready to play.Alot of cats these days turn their amps on then immediately hit the standby switch My humble opinion is this is the wrong way or technique.I would like to hear other opinions on how they get their amps warmed up.......hopefully not sidetracking this thread but adding to the discussion at hand!
