Although I have a nice B2 prototype Barker, I've been using a double bass for bluegrass, since it's the traditional thing to do. However, I'm finding that the upright double bass is exacerbating a carpal tunnel condition in both my wrists. So I switched back to my B2 prototype and paired it with a Behringer acoustic amp. While it's not a true acoustic bass sound, it's a good sound. And it cuts through the other instruments and the vocals in a bluegrass band very nicely. It's an assertive bass sound, but not overwhelming. And it's so much easier on my hands and wrists. Anybody else have experience with a Barker bass in a bluegrass setting?
