i had never seen this finish in real life before either, and i had only seen a Q6 with a 2tek maybe once or twice before online. i got this one on ebay a few years ago. it came with a hell of a lot more dings, chips and scratches than the seller admitted to (among other inaccuracies and neglected details

), resulting in my paying a higher price than i would have otherwise. but in the end im really glad that i went ahead and bought this bass. it plays like a dream, sounds great, fits in my mixes better than anything else i've tried, looks very cool, and i feel quite lucky to have one with a 2tek.
each string is almost its own string-through bridge. each saddle screws into a big fat "finger" of metal which extends through the body and down to the master bridge plate that mounts on the back of the bass. however the strings are run through holes in the fingers that start a little less than 1/2 way through the body. so the bridge goes all the way through the body, but the strings only go part of the way through.
the 2tek definitely adds a considerable amount of weight to the bass, but it also seems to add extra clarity and definition even to a modulus. the one catch is that with the B string set as low as it can go, the saddle does not pull back far enough to intonate properly. it starts to go out at the 7th fret. i dont normally play my B much higher than that though so its not a big deal for me.
i'd love to try a fretless Q6 with a 2tek, if i can ever find one. though for that matter, i'd love to try a fretless modulus at all. i've still yet to get my hands on one.
by the way...what number are you up to in the modulus mob?
