Hope you guys can help me out. Here goes. Got a Steinberger XZ 25 from Music Yo, its a cool little bass that sounds good, HOWEVER, it's passive and I would like to convert it to active. Also it has the double ball end string retainer at the tip of the neck that doesnt allow for normal string use. NOW here are my questions; 1.Can this bass be converted to an active, and if so HOW, its got EMG select pups in it. Could I just add a preamp? 2. I know Steinberger has headpieces that allow for use of single ball end strings. so can they be ordered, and will they fit my bass which has a narrower string spasing than the Synapse? Please share your wisdom.
