I'm glad you brought up the Sans Amp Acoustic DI. I've always wondered how that unit sounded with upright bass pickups...piezos that is.
So, the Focus SA is cool little power amp version right? And you thought it was a toss up between that and the iamp 500?
I can sincerely appreciate the need for speed when utilizing public transportation -- as I lugged my upright and a smaller Trace Elliott head all over Philly when I was in school there...a serious drag. But since I'm mostly a SUBurban dweller these days, I don't mind toting the extra weight of a solid sounding head.
I have looked at the iamp500 -- but might opt for the 800 just for the headroom.
I guess I'm gathering arguements for the Euphonic stuff -- mostly because of its power and tone shaping possibilities.
In all honesty, the more EQ the better. I play in so many strange settings (don't we all?) that I often find myself tweaking out gnarly midrange or boomy lows to compensate for the room acoustics.
I wish I did strictly quiet jazz gigs, but most of the stuff I do can get kind of loud loud -- especially when working with caffinated drummers and "lead" vocalists -- even on jazz and swing jobs. I hate when my fat acoustic sound goes to crap past a certain point. I've found, the nicer the rig, the better chance you have of maintaining stability of sound at higher volumes.
I want an amp (and speaker rig) that's super versatile and can cover most every gig.
Your Tech 21 and FSA sounds like a hip, portable rig though!
