What are the opinions out there regarding an amp for small gigs, for both electric and upright bass. I currently have a Mesa Boogie Walkabout - love it for most stuff however it's pretty darn heavy. What I'm looking at is the Acoustic Image Coda and the PJB Briefcase. All things being equal, a two channel unit is attractive however now manditory, I have a BassBones to split the signal - EB/UB. Great tone is manditory. I play mostly open mics with a singer/songwriter, some small clubs, 80% UB Eminence or Christopher 7/8 Busetto, 20% Fender Jazz Bass. I use Gage PU on the UB's.
