This is an early low serial # U.S. Masters EP-42 It is an absolutely beautiful bass, a pleasure to play and look at. Made in Wisconsin of the finest materials money can buy, it has that custom shop quality to it. Completely passive, yet the EQ voicing filters give many tonal options found normally on active basses (see last pic for explanation on control layout). I'm a Fender/G&L guy yet I absolutely love this bass. The neck is silky smooth and super comfortable. Width at nut is 1-5/8" and scale length is 34". I believe the fingerboard wood is purple heart. Weight is a very comfortable 8.6 lbs. The Sperzel locking tuners are really cool too so you spend less time winding. Comes with original form fitted case with case candy. Has new D'Addario Xls with med/low action. Excellent condition. Has a small amount of tarnish on bridge that is barely noticeable. I've never gigged with it and it stays in its case in a smoke free studio. I hate to see it go but I'm playing less these days and would rather have someone else get more use out of it. Asking $700 shipped West of the Rockies $725 East.
