I just bought one used from GC. It was at a price I could not pass up. Y'all can look up the specs so I won't go into details here. Suffice it to say it is a 5 string, narrow spacing, 34" scale thin neck with fret lines and a single humbucker 3/4" closer to the bridge than the Musicman sweet-spot. Active, B/T preamp. Simple bass. Overall weight on mine is right at 8 lbs 2 ozs. It balances well with no neck dive despite the 5 tuners hanging on the headstock. Speaking of tuners, they are strange. Each tuner has a three bladed knob on it. I find I really like it. They are easier to grab and work well. How's the low B? I've only played at home but so far the B seems - OK. Not great. Not like my old SB5000 or the Lakland 55-01. But for the few times I need a low D I suspect it will be just fine. Of course as a fretless everyone will want to know "does it mwwah"? The fingerboard is (I'm pretty sure) ebanol. The bass has roundwounds on it right now. I adjusted the action, flattening the neck curve and lowering the strings. Yes, it gives a nice mwwah. It isn't this big obvious bloom but there is a distinct fretless mwaah voice to each note. The D and G strings sing the best in that regard but even low G on the E string has a woody mwaah character to it. In fact I've tried to coax a "fretted" sound out of it and I'm having trouble. Even if I finger a note hard with the L hand and pluck closer to the bridge it still has a bit of a bloom and enough mwaah and soft attack on the note to say "yes, I AM fretless". If I go easy on the fretting pressure and pluck further up the neck I get even more of it. I have about 30 days to decide keep / return. I went to the store fully intending to not take the bass home with me. Once I got it home, I fully intended to play it for a few days and then return it. It has been a few days an my intentions are no longer clear. It is not my ideal fretless bass but it was low cost, plays and sounds quite good and has some cool features. I may have to hang on to it for a while.
