My wife and I are downsizing so we can move onto a Catamaran - so new gear acquisitions come with a stipulation of it takes up very little space. The Roland JS-10 comes to mind, but I haven't seen/heard anyone playing a bass through it. The other option it seems is the MarkBass Micromark 801. Need something I can practice with in a....uh...confined space and take to jam with friends...maybe play in very small venue with it... Thoughts?
