Thanks Boinkeee for sharing all that info. For me, I don't find myself using the 4way foot switch..as I am close enough to the amp to change settings on top. As for sudden volume increase for leads..I just dial up the Volume knob on the guitar for that, as I have done the Treble beed mod on all my guitars. If it ever came down to me needing to switch to a different sound altogether in the same song..then the foot switch would really be handy for me..but I just try to keep it simple when playing live.
