Aluminum! (Or Al-U-minium to our British friends.) The Kramer Vanguard Bass has a neck made of Aluminum with wooden inserts (to lighten the neck). Made in USA, Medium scale length, a Zero fret made of patented Petillo fretwork, Maple body with a Cherry finish, a solitary DiMarzio pickup and 24 frets. She has a hole drilled in the back where an adventurous person put a strap button in a weird spot for balance.
Rock like Jeff Pinkus does. NOW!
