I will be getting one of these heads soon, and was wondering if anybody who has used, or still uses this head would share any thoughts, tips, etc. ? I found the old MusicMan site message board, but it seems to be more about the guitar heads and combos. I found some rather oddball stuff, like, the " Normal " channel is supposed to be for Bass, while the " Bass " channel is for bass guitars with darker sounding pickups, or generally darker tone ( according to some posters ). Also, each channel has two inputs, which are supposed to be different as far as " tone " goes from each other. One of the techs on the site recommends that the amp be used at " low " power in order to save tube life. He claims there is no discernible difference in volume between the two settings. I could not find a definite answer to whether or not the tone stack is like the Fender type, only that, turning the bass/treble/middle knobs all the way to the left, results in no sound at all ! Anybody care to comment on any of this, or add some other info ? Thanks. Can't wait to try this head out, as it will be my first tube head in about 30 years !
