I owned & used a Roland Micro Bass Cube for about a year, plenty of effects/modelling but I found it lacking (a lot) using my passive P-basses. I found it only really usable with an active bass, I liked my Skjold through it. The 'tap - - tap' to set the beat/time for the drum machine drove me mad, could never get the timing spot on, never understood why not fit a rotary 'speed' control?
I bought it to keep in the sitting room, ready for the ocassional playing along to the TV or DVD, it never got used bought & sold on here for about £100 IIRC, so if you can get one 2nd hand to try you're not likely to loose a lot should it not meet your expectations.
From what I recall - trying Fender amps like the Bronco 40 you might find it the better sounding amp - but worth trying a few in your local shop if you can before splashing the cash. I had a Trace Elliot Boxer 65 a few years back, about £75 off ebay, now they're a decent practise amp

Practise amps are one thing I think you can get a reasonable idea of in a shop environment/music room.
