Thanks for the info, Jimbo!
The Micro Cube Bass RX is exactly what I use with my little 23" scale Gold Tone Microbass:

I never liked ukulele basses, but this thing looks like it's a different league. Do the strings "stick" to the fingers like it happens with ukulele basses?
Big box? Haven't used one since I got my first B-15. We were our own roadies back then and the Portaflex made life a lot easier. Not only that, it sounded much better than the big box monstrosities from Traynor, Fender, Marshall, Vox, etc.
My little GK is all I need now. Any larger venues and I simply DI.

If I do get a big box, it will be to move some air in my decently sized live room. The box itself will hardly move from there! :-)
