hi all. after several years of absence from playing bass, i am about to re-enter the world of making music. i have: g&l 4-string (effectively a music man copy), some taiwanese fretless, a neuser neck-through 6-string an acoustic double bass. the latter to are my main focus. i used to have a GK 700RB/ Mesa 2x10 EV setup. i still have an SWR workingman 15 combo. the SWR is very loud given its light weight. yet i find it to be too large to be carried around on public transport. an i find it to be inappropriate for amplifying my double bass. i am looking for a combo amp that would do the following: -be lighter and smaller than the workingman -be a good or very good double bass amp for latin style music and jazz -be good enough for my 6-string for band rehearsals, jamming and small clubs gigs (i could buy some cheap extension cabinet if needed) -be not too expensive. i would probably think about selling the SWR. i have done some www search. how about these: -hartke kickback 10, kickback 12 -GK backline 10, 12 and MB150 -SWR WM 12 -SWR LA 12 your input is appreciated!
