I'll have to weigh the thing, but let's just say that thank goodness I've been working out. It's a 5 string ash body, what do you expect? Construction is fantastic. Real MOP block inlays. Tight neck joint. Smooth finish. Excellent grain on the ash. The (9v) preamp is better than I thought it would be. Boost and cut, but not sure about which frequencies. I think it is a standard Ken Smith BT preamp circuit. I tested it out with the preamp set flat and alternating between passive and active (flat eq). Other than an obvious increase in volume from the boost, I did not detect any additional coloring of the tone. Fairly transparent, which is ideal in my opinion. The boost and cut for bass and treble were usable over the entire boost and cut. Some preamps seem to boost frequencies beyond any usable levels, but not this one. Lots of different possibilities. Haven't played the bass enough to get a good idea of the pickups. I did discover (as stated earlier), that I can easilly fix the (neck) pickup misalignment. (It is only noticable because I am obsessive about things. Not a big deal at all. Does not appear to affect the tone at all) I'll have to trim the pickguard a (tiny) bit to make it fit if I move the pickup, but that is ok. It's getting replaced anyway (tort). The pickups definately seemed to have more bottom than other standard jazz pickups, but still gave a good jazz tone. There is some hum when the balance isn't centered, but I am having a bit of rewiring done and will use star grounding to see if that helps out any. If not, it isn't too much hum.
