had a few small practice amps and all were quiet disappointing to be honest, so I now have a TC electronic BH250 2x8 combo small light and under £250 best sounding amp I have owned IMHO. tried the two small PJB combos (the size of a shoe box) high quality but no caricature to the sound, found the Markbass to be the same although it was the 601 that I tried. both are very clean sounding and both are very expensive ! there are the new table top type guitar amps you could look at too, things like the Yamaha thr10 and the vox soundbox mini, both have bass guitar amp models built in and a range of effects but at £150 to £200 a go I cant see the point myself except possibly for the run on battery portability that they offer. there's also the Roland micro bass RX in that category too, they got a lot of love at one stage so I got one. returned it after 2 days! Took a Roland micro cube with me to the states when I went to work there for three months and that did much better than the bass RX.
Only one way to know that's take your bass n go try a man as you can
