....Regarding maxing out the Master on a Blues Junior

[89strat]

I read a lot back and forth on diming the master volume on a Fender Blues Junior and using the regular volume to control volume level to get a more open, less boxy tone. Others prefer using the Volume to get some some grit and just use the master to control overall volume, to get more break-up tone. Not to get off on which sounds better, I'm more interested in your thoughts on how they feel. How does maxing out - or not maxing out - the master volume affect your playing. For a basic somewhat clean full tone, are you getting more sustain, touch sensitivity, etc... maxing out the master volume, or by backing off the master but upping preamp volume.
