I just picked this up yesterday. It really is quite an amazing bass on many levels. Here are a few pics:
My first impression upon opening the bag....it's a VERY well-built jazz bass. I have had LOTS of jazzes over the years, as well as an LEJ from a few years ago. In fact, I believe I owned the first 4 string LEJ...an old tobacco burst with Sadowsky-like 1/2 guard. I picked it up at a NAMM show several years ago directly from Brian. Here's a pic:
Anyway, the bass has a couple of features I didn't think I would like; in fact, they are features I would NEVER order on a bass.
#1...mahogany body. Most mahogany bodied basses I've played lacked mid character, and had a scooped EQ-like sound to them.
#2 a 2 band preamp. Why the hell would you NOT have the mids on a preamp, especially on a jazz?
#3 humbucker j-style pickups. If it's a jazz, why not put single coils in? My plan was to put the LEJ singles in.
#4 the benevente preamp. I have had a couple of basses with the preamp in that I couldn't get my sound out of, which is a very bridge-heavy, Jaco influenced tone with a lot of mids, but with bass added. Essentially, Jaco on 'roids. I was thinking of swapping the pre out.
Well, I HAVE to apologize to Brian Barrett. I feel honestly, quite stupid. I got the bass yesterday, did a full setup on it, and decided to take it to my Friday night gig, which is a jazz quartet setting that plays almost every tune in the Real Book to old funk and R&B standards, to some hipper, newer style tunes. Well, I have to say........................
THE BASS KILLED. ALL NIGHT LONG. By using the 2 bands with the series switching on the pickups, I was able to get any tone I needed, and the sound cut through like a hot knife. The bass takes a deadly-low setup, so I was happily grooving all night long in total comfort, and when I took solos, I stood out with outstanding tone and presence.
The mahogany body has PLENTY of mids, and the character of the pickups which I didn't think I'd like (bright edge to the front of the sound) is what made me so audible out front! The preamp works like a charm....I just learned I need to think differently than I would if I was using a 3 band preamp. It was ME that needed to change! I have been a 3 band user for so long, I never thought I would have any use for a 2 band pre. Man, was I wrong!

All in all, I am digging this bass A LOT!!! I can't wait to play it again tonight at my trio gig!!!
My only "complaints"....
#1 The passive tone roll-off. I wish the cap was a higher value so I could roll a bit more highs off if needed.
#2 The pickguard....gotta change it out to aged white pearloid. Not a fan of tort on anything but burst or white, but that's my bag.
So, in short, I AM SORRY, BRIAN!!!!

I'm digging your bass, your pre, your pickups, your haircut, (well, maybe not the haircut!)

I am digging my new LEJ!!!
