1994 Modulus BSQ6XL-SS Quantum 6 String Bass Cocobolo Top Carbon Fiber!

Here's a pretty rare bass from Modulus back in the early 90's! 6 SPi Sweetspot Standard... We recently got in a large collection of choice, unplayed and well-preserved fine guitars and basses. One owner since new. Time capsule piece here. This has to be the nicest of this model you'll ever find! It plays and sounds excellent. Comes complete with the original case and paperwork as shown. This is the bass match to the Bob Weir (Grateful Dead) guitar coming up soon.  

Condition: Minty. No wear of note. One owner. The bass looks nearly unplayed or played very rarely.

    Weight: 9.8 lbs.
