So I just tried out a 4-string Grendel at a local store that felt pretty good, and the tag on it said $519(I think). It's not a new bass, and has some wear, as I can tell by the slightly tarnished upper frets. It has a decent neck and a great sound palette(active preamp I assume - a 3 way switch and knobs for volume, mids, treble and bass) from the bartloni jazz pups. I don't know a whole lot about the Grendel but have heard many great things about MTD's in general. It's already in a decent price range for me I suppose, but I just don't know what these usually go for. Whaddya guys think?
