Brilliant place! Went in to get my Output Jack fixed. The guy was really quick, and took the time to explain everything to me and teach me how to do it myself in future. I also got my strings changed at the same time! Would highly recommend! Great price too!

Had my Yamaha cpx1200 repaired which had two large holes in the back of the acoustic guitar. Martin hard work craftsmanship is out of this world. I had visited many luthier's who would not take on the repair and the cost does not reflect the quality of repair that has been completed.
