Another vote for Acoustic Image products, they were designed by a double-bassist for just that application. Number of options available, especially if you plan to use your Barefaced BBII for a speaker cabinet (probably an excellent choice). One thing to keep in mind with some of the Acoustic Image combo amps is that they can only be used with a four-ohm extension cabinet. I don't think the standalone AI amp heads have that kind of limitation. I own an AI Coda R combo amp and one thing I love is the notch filter, makes it really easy to negate the effect of a boomy room. The Coda is one amp, though, where you can only use a 4-ohm extension cabinet. When I got the Coda R they hadn't started making the Ten2 combo amp or I would have definitely gotten one of those. IMO the AI products are a better choice for amplifying any instrument with acoustic properties than a conventional bass amp, but naturally that is based on what I like to hear.
