Located in Flagstaff, the mountainous and forested landscape of northern Arizona, we specialize in string instruments. In operation since February 2004, we have quickly become the premier fretted instrument repair shop and warranty center in northern Arizona for many top brands. We have a wide variety of instruments and accessories for acoustic and electric musicians alike. Custom Sound Instruments is a progressive music store that still values the tradition of personal service.

We strive to maintain a sense of community and offer many activities such as lessons, repair seminars, concerts and more.  We aim to fulfill the needs of independent musicians looking for a store they can enjoy and be a part of.

Our specialty and main focus is the repair shop where we handle all kinds of repairs on many different string instruments: guitars, basses, banjos, mandolins, violins, dulcimers, ukuleles, and more. 

Shopping is different these days, and not only in the music world. The  big-box-store, warehouse mindset, is pervasive.  Conversely, we strive to make business with Custom Sound Instruments  an interactive  experience with personnel pledged to customer satisfaction before and after the sale.
