bolt on 19 mm spacing just-a-nut the input jack is a tad scratchy and there is a small surface crack on the back of the headstock, but that dosnt affect playability or tone at all. received it ina trade recently from a fellow TBer but after my second 6er, i dont think i can handle them and will stick to 4's and 5's for now. comes with a warwick hardshell case. trades only. what im interested in: 4 and 5 string basses +/- cash depending on what is offered. the only 6 strings i would be interested in would be a benavente singlecut standard, or an mtd Z 6 plus cash also interested in bergantino 2x10 cabs, epifani 2x10 cabs, thunderfunk heads, anythign to do with the word lakland.... shoot me offers, just testing the waters.
