Very Rare Mid 80's Original Quantum Modulus PJ (originally posted "TBX" which was an error.) 35" scale 8.30 pounds 24 frets Alembic P and J pickups into a active on-board 9 volt pre-amp. The "tone" control sounds like an active filter, wide open you get tons of hi-fi sparkle, dialing it back slowly gives you some vintage tone that cuts through but sounds like a old school bass amp, "no tweeter" vibe. The range of tones on this bass coupled with a simple straight forward pre-amp is incredible. The low notes ring out like a grand piano, and the overall character of this bass is what you would expect from an instrument with this pedigree. No truss rod. Condition: The neck is in great shape, as are the frets especially for the age of this instrument. Body has scratches and a couple of gouges. This bass has seen some action. I adjusted the action, intonation and put new foam under the pickups. No trades, for sale only. Please private message me if you plan on making an offer.
