Noll Guitars is a shop on Macklin Street owned by Stan Bienkiewicz, an expert at building, repairing and restoring fretted instruments. Stan Bienkiewicz cautions that a guitar is similar to a human being in that we both need food, water and care in order to survive (food meaning to play your guitar every day). He also believes that a good guitar can be killed if it is not properly cared for and that is why he recommends that all guitar owners get their guitars inspected to check for problems that they may not be aware of. Additionally, the shop does upgrades for guitars and has demo guitars available with special equipment such as pick-ups, bridges, locking heads and more on them to hear how an upgrade will sound on their guitar before they purchase and install it. The shop also sells guitar pick-ups, strings, tuners, instructional books, guitar cords, amplifiers, bongos, t-shirts, guitar straps, CDs, guitar picks, magazines and more.
