As the title suggests, I am putting up for sale my 2005 Modulus Q4. It is a dream to play! The only reasons I am selling are (1) I am unemployed and (2) I need to pay down my credit card because my GAS has gotten the better of me... I really hate to get rid of her, but times are tough!!
The bass has dual EMG pickups with what I am pretty sure is the EMG model BQC preamp. Control layout is:
-Volume
-Pickup blend
-Stacked mid control with sweepable mid-shift ($50 upgrade)
-Stacked treble and bass
Chechen top ($300 upgrade) and fingerboard ($100 upgrade), black hardware.
Sorry, no trades. 
The bass is near mint in look, feel and sound. In the interest of full disclosure, though, it had an odd buzz when I bought it and Mike Lull shimmed the nut when I still lived in Seattle. It fixed the problem perfectly.
$1,800 shipped and insured CONUS in a Modulus hardshell case and with a fresh set of Mike Lull nickel strings.
Thanks so much for your time.
