No need spending big bucks when these are available for $300 or so used...I'm talking the older models with the superior Aphex System electronics, Aural Exciter with Big-Bottom Sound.
Not another bass made with the Aphex System!
When it comes to solid-body basses, there are quite a few I can recommend, but when it comes to acoustic basses, even though I've tried out more than most people, I simply cannot recommend anything else.
(By the way, I own two and wouldn't trade either one for a Martin, Guild, Warwick, etc...D'Addario black tapewounds on both.)
Headphones are recommended.
Good luck, and whatever you do, don't listen to the detractors and their "Acoustic basses are useless " bs. That's been proven wrong time after time after time.
