Two great ideas which I'd not considered, I'm a bit confused about the sonic benefits of 18v though. As I understand it, the headroom is increased, but forgive my ignorance, what does that mean in real, noticeable terms........is the output increased? does the tone of the bass alter? I assume the increased headroom is a benefit when recording (which I do a lot of at home ), but does it make much difference playing live?..................Thanks for your input gents!..............Very interested in your Dirty Jazz 5, Rumple, I'm a big fan of Delano's !
