Re: How do you feel about an acoustic bass guitar in your jam?
I second the thunder chief. A few years ago I want shopping for an ABG and I played them all including the Taylor. The Tacoma was the only one you could hear in an acoustic jam situation. It also came with a passive piezo and sounds wonderful plugged in at a low volume.
However, I found that it only sounded good with Elixer strings that are pretty expensive. I got about 6 months out of a set. Also I was not playing it in a Bluegrass setting. I am not sure how it would stand up to a banjo and a mandolin.
Edited to add, if you can find an old Ernie Ball Earthwood ABG those will also stand up acoustically.
