I looked this Modulus up on GC's used website. It's an older model non truss rod. It's more than likely 17mm spacing. The pickups are EMG DC soapbars probrably with an EMG 2 band preamp. Check the serial # on the back of the headstock the last 2 #'s should indicate the year that it was made. It's a nice bass. It looks like it was defretted and made into a lined fretless. IMHO.
Thanks, I had checked earlier but didn't find it.
