I have to say that I considered getting a DB again (had a Thomann 22 originally but didn't have the space) but wanted something smaller, something that sounded great amplified and that played/sounded like a DB. I also didn't want the hassle/expense of having to get it setup. The BSX has an adjustable neck which lowers or raises the action to how you like it, a 3 band EQ and isn't much bigger than a normal bass guitar when the end pin is fully in. These were all plus points for me over a DB, which considering if I bought a decent ply/hybrid with some decent strings, a setup and a soft case might have been around what I paid for the BSX!
Also reading reviews of what Mike Pope and Brian Bromberg have said about the BSX and the fact that they use one live instead of their acoustic DBs was also a major factor!
