Modulus Quantum RARE 4 string Q4 From Modulusguitars.com:
With its massive sustain, Earth-shaking low end, and versatile tone controls, it's no wonder the original carbon fiber neck designed by Modulus has become the first choice for many of today's top touring professionals. The most important advance since the invention of the bass guitar has been the carbon fiber neck. From that day in 1976 when bass-playing rocket scientist Geoff Gould (yup, he was a carbon fiber designer on the Voyager probe) first wondered, “What if ...” the electric bass has been a different animal. The Grateful Dead’s Phil Lesh played one of the first carbon fiber-necked basses and from that point forward, the most accomplished and creative bassists in the world have played a Modulus. To this day, Modulus Quantum basses are made using the same aerospace “hand layup” process as in the beginning. We’ve made many subtle design improvements along the way, including the addition of a two-way relief adjustment. Each neck is still hand-laminated with layers of carbon fiber “pre-preg” and cured in the Modulus autoclave. The distinctively spacey exterior layer of carbon fiber is known around the shop as KLDTM or “a thousand (k) ladies dancing.” This artistic touch has been a Modulus trademark
for decades. We don’t usually like sweeping statements, but Quantum instruments tend to be brighter, with an extended harmonic mix. Genesis instruments tend to be warmer, with a greater fundamental pitch focus. If there’s magic in carbon fiber, it’s in the very high “modulus of elasticity” of the material. In plainspeak, carbon fiber is extremely stiff for its weight – perfect for a bass neck. On the performance side, each note is full, with low and high harmonics in generous quantity. Plus the high resonant frequency drastically reduces the possibility of dead notes – even when playing the low strings in the high register. On the maintenance side, carbon fiber is impervious to moisture and resilient against temperature changes. Your Modulus is perfectly stable from Montana to Miami.
As you can see, it is in impeccable condition for an 11 year old instrument (built in 1999, yes it has a trussrod). Comes with OHSC and Warrantee registration card. I would guesstimate its weight to be right around 9 lbs. I love this bass, the only reason I'm looking to change is because I like 5 Strings more, neck pickup tones range from killer P-bass to the best of anything in the modern world. The bridge pickup cuts like a knife. Top notch construction and playability! Currently set up with low action (.060" or approx. 1/16th of and inch action @ 17th fret) with a newish set of DR black beauties (coated).
I am looking for a trade for another bass (no amps please, I'm covered ).
Possible suspects could include 5 or six strings maybe fretless? anything modern or a vintage fender 4.
or
for a nice Apple / Mac computer it must be newer and intel based processor I was blown away with how great of shape this bass was it is clean !
Please PM me with what you might have, who knows what could happen! I would also like to note, there are no problems with +/- cash to make the deal work .
