About Us

CornerStone (Front View)

CornerStone Music is a musical instrument boutique located in Clermont, Florida.

We strongly believe music makes our world a better place. So—through quality products and great customer service—we’ve made it our mission to help people find the best musical instruments they can afford. Guitar has become our niche, so we offer quality entry-level guitars for beginners and novices all the way up to the finest boutique guitars for professionals, collectors, and enthusiasts. We also carry basses, amps, band instruments, percussion, sheet music, all sorts of accessories, and more. Every instrument receives a thorough setup and inspection before it reaches our showroom.

We also offer specialty services including: private music lessons, band instrument rentals, guitar repair & set-up, instrument appraisals, consignment, and much more.


Pete Bonaskiewich

Store owner Pete Bonaskiewich is our resident guitar guru. He’s been highly-sought as both a guitarist and guitar instructor since 1993. After years of playing professionally, he decided to dedicate himself fulltime to CornerStone Music. Pete has an uncanny ability for helping people understand the guitar. His favorite musical styles are rock, country, and blues, but he’s equally at home with classical, pop, funk, and standards.

Kris Muszynski

Kris joined our staff after studying guitar with Pete for many years. He’s become an integral part of our team, teaching guitar lessons, repairing instruments, assisting customers, and other day to day tasks. Kris is what makes the whole operation run smoothly. (As smoothly as it can.)

Nick Allen

Nick Allen has spent years playing professionally in his band Soul Switch. We are very pleased to have him teaching here on a regular basis.
