I'm also using EA gear - a single Wizzy 10 cabinet, with an Acoustic Image Clarus amp. My band situation is kind of transitory at the moment, so I'm not using it for a steady gig currently, but I've used it in a number of different situations.
In small venue gigs, with an unmiked drum kit, and other instruments miked through the PA it generally does a great job. With one particular drummer (who comes from a metal background), I feel as if I'm about at the limit of this rig though. On larger stages with a DI output to the PA, it provides plenty of level as a monitor, unless the sound guy has put lots of drums in the wedges, at which point it struggles a little. Provided I'm in a situation where the volume is sufficient, I'm very happy with the sound of this setup - it's very clear but not overly harsh in the high end. I think my ideal situation would be to have two of these, and leave one at home for smaller gigs.
I get the impression that the fundamentals of the lowest few notes are a little shy with this cab (compared to listening to a recording of my bass pickup signal through studio monitors), but those frequencies aren't that prominent in the acoustic sound either. So the low-end roll off of the cab probably helps to tame the pickup sound somewhat.
