well fine, if you dont want Peters Lefty Board or Andrews Lefty Board, then we'll name it JOE'S LEFTY BOARD. I'm definitely happy with that.
The store I bought my lefty Traben Array 5 String from is pretty damn lefty friendly too, meaning he stocks or can order a bunch of lefty stuff for you...www.adirondackguitar.com
This was the ONLY place I could find that had a left-handed Traben 5 string...he also stocks the four string Phoenix model (which I will get also...those are the ONLY two models made lefty by Traben btw)...I hate to sound like a Traben fanboy, but I really think they have a great thing going with their basses and they look different...aggresive, yes, but still, they have some classy designs.
Check out
http://www.southpawguitars.com for the Mecca of left-handed guitars...they also stock basses too.
http://www.basscentral.com also has some upper end basses for sale, left handed, and the local music shop here in Denver stocks stuff too (
http://www.drumcityguitarland.com I think thats the site)
Cheers.
