I recently bought a used Emminence EUB. the g string was a little "weak". I changed strings, no diff. Called G.Edward Lutherie, and Gary Bartig. Even though I bought it used, Gary took the bass and fixed it up for me for only the cost of ONE-WAY shipping. At the time he said it sounded like it needed a sound post adjustment. (It did)he fixed that, AND he REPLACED the end pin witha neat anti-rotaional one, and made the output more secured to the tailpiece. BTW- it sounds great. It's just what I was looking for to get my feet wet with playing upright. So if you want a good EUB and want customer service then I strongly suggest you take a look at the Emminence. http://www.gelbass.com/ Thanks to Gary
