I've had this bass for about 8 years now, and I've grown to really love it. I'll just say a few things about it.
The neck has a really long scale length, big frets, and a flat "D" shape. The back of the neck is unfinished—except for a light oiling. This bass doesn't have the fastest neck in the west, but it's fast enough to smoke a cowboy or two. The fretboard has somewhat narrow string spacing and a relatively wide radius. It would be a great neck for a pick player, and it's also really great for finger-style players that play double-stops, arpeggiated chords, or complicated runs in the high register. Slap players would probably want something wider.
The body has smooth, comfortable lines that hug the body. The cutaway near the neck pocket gives you plenty of access to the highest frets. It has a 35" scale length with 24 frets. That's huge. It's not too big for me (I'm 6'2" with a big frame), but it's not small either. I do wish there were less of a hard edge where my right arm hugs the body, but it's not a big deal.
The EMG-HZ pickups at first seemed like nothing to write home about. They're dead quiet and flat in frequency response, but the EMG Active EQ/preamp isn't very good. Even with two 9v batteries, the output was weak and muddy. I took the preamp out pretty soon after I got it and put them in a passive circuit. They're bland with 250k? potentiometers, and almost as bland with 500k? pots too. For me, these pickups sound best with 1M? pots. I get lots of midrange snarl, and more than enough low-bass presence.
My favorite thing about the bass is that it is resonant. The body is mahogany with a maple top, so I figured it would shake well. I'm not sure that a bass' wood has an effect on the picked up signal—if it does, you couldn't hear it in a recording or over a speaker—but it certainly does have an effect on how resonant the instrument feels against your body or unplugged. So, that's a positive.
