For Sale: 2005 Modulus Quantum Q6 six-string bass with hard-shell case. $2200 shipped UPS ground to contiguous United States. Pick it up from the Bay Area, California and I'll let it go for $2000. Green-Blue transparent burst over a AAAAA quilted maple top and what appears to be an Ash body core. Bolt-on carbon-fiber neck. Excellent condition. Details below. I put new strings on it (Modulus branded strings) back in 2008 when I got it and then didn't play it again since then. This is an awesome bass and sounds fantastic. I think I paid $2500 for it back in 2008. I only played it for about a month and maybe did one gig with it. Hi-res photos available at: http://unpronounceable.com/basses/modulus/ The only imperfections I could spot are: String wear on the neck pickup by the low strings. See photo DSC01950.JPG There's a tiny ding on the back near the effects cavity. It looks much worse in the photo than it is on the bass due to it being blurred in that photo. See DSC01959.JPG . There's another small ding near the strap button in photo DSC01961.JPG. What looks like a scratch near the input jack in that photo is just a smudge. It wiped clean. There does appear to be some minor markings that you can only see if you hold it up at the right angle in the light. It was probably wiped down with a towel or something at one point which left microscopic imperfections. It's probably not something you'd ever notice unless you were inspecting it very closely. The perils of a gloss finish, I suppose. You can see this in some of the pictures.
