It's time to put up my 1990 Modulus Quantum 6. I have come to realize that, since my work-related wrist injury last year, I can't hang on a 35' scale bass for a whole session consistently without pain, so this beauty has got to go.
I got it about half a year ago from a fellow TBer. At that time, it needed some TLC and I chose to do some upgrades as well. It used to be the Modulus standard early 90's 3-hole EMG system. I wasn't happy with the single coil EMGs and the EMG BTC 2-band system, so I had the following done to this bass:
All electronics removed and cavity cleaned and shielded
4th control hole and 2 DPDT switch holes drill pressed into diamond plus two switch pattern
All from bestbassgear.com: 2 Bartolini XXM56C Deep Tone Quad Coil pickups, Aguilar OBP-3 18V pre-wired volume (active/passive p/p), blend, stacked Treble/Bass, midrange (400Hz/800Hz p/p), each pickup has parallel humbucker/single coil/series humbucker 3-way toggle switch
solid ebony wood knobs
More specs:
Turquoise quilted maple top (
SUPER cool top...areas of tight quilting fade into stretchy looking maple grain and back again!)
Carbon fiber neck (no truss rod, but action is great)
17mm string spacing
1.982 in. nut width
~8.5-9 lbs on bathroom scale...super light 6er!
This bass has been played (note the surface marks on the back of the bass in the picture), but still looks good where it counts. While there may be some bumps and bruises, the top still looks great and the back of the neck doesn't have any pot marks or any 'feelable' blemishes I can find. It's super light and comfortable sitting and standing, and the recessed straplock on the upper horn is a cool touch.
This bass sounds amazing, and has a great amount of tonal flexibility. 9 pickup wiring combinations each for active and passive modes...did I mention the flexibility? Soloing the bridge pickup on series humbucker mode gets an agressive, biting MM tone, and while the dual single coil mode doesn't sound like a traditional jazz, it's got a clean, coolness to it as well. If you've heard these quad coil barts before, you know what I mean. I'd prefer this pickup layout in a new bass, but I'm ready to open my ears to other pickup brands/types as well.
Here's what I'm looking to trade for, in order of importance:
34' scale
fretted
5 strings (will consider 6 stringers also)
Natural wood top (will consider translucent stain)
Flexible pickup config (no P, MM, or P/J, please...been there or still own one)
I prefer modern looks and sounds (Delano, Bart, Nordy, etc.)
No fret markers on top of nicely figured fingerboard
I'd be looking for a
trade value bass around
$1,700 (I'm willing to give a little or get a little cash), or for
outright sale, $1,850 shipped with a deluxe gig bag with neck block.
Feel free to shoot offers and trades and questions. I love the sound, weight, and unique maple top on this bass, but my wrist doesn't.
FS/FT: 1990 Modulus Quantum 6, Bart Quads and OBP-3 
Sent you a PM on this pretty girl. Only question is about it not having a truss rod. Any issues with these types of necks going bad due to no truss? If they do go bad are they fixable. Anyones input would be greatly appreciated on this.
