Avishay (Avi) Shabat graduated from the Algranati Guitar Making School in Israel before moving to Los Angeles to apprentice for guitar repair shops and work for a boutique guitar company. Avi spent the next four years building handmade instruments, and founded a company of his own, Guitar Groomer, where he restored and repaired guitars and basses from his home workshop. In 2012, Avi expanded his repair business and began designing and building his own instruments, launching a new line of handmade electric guitars and basses—Shabat Guitars.
