Is there any special advantage of an accoustic bass guitar than, say, a solid-body fretless bass guitar? I'm moving away from playing an upright bass at church because of health reasons (arthritis). Our folk group director suggested I try an accoustic bass guitar as striking a happy medium between bass guitar and capturing some of the accoustic flavor of the upright. BTW, the upright had to be amplified, so there was no intent that I play an accoustic bass guitar without amplification. Electric uprights are out of the question because I need to move to a shorter string length. Thanks for your thoughts on this, Brian.
