I'm going into multistrings in a big way. I recently got a hold of this little beauty: It's a Santucci Treblebass. It combines a 4 string bass and a 6 string guitar on a single neck. It's usually played by tapping but I'm sure conventional playing will work too. Neck scale is 27". Here's a closer pic. Note the P pickups on the bass side. And how about this headstock? I'll post about it when I get it. I can't wait for it to arrive!
