From the reviews

The floating bridge on my Fender Jaguar guitar was a complete mess: the saddles wouldn’t stay put, screws were falling out, and the strings rattled. I was about to give up on my guitar until I went to Mark.

★★★★★ — Julia, Oct 2023

Appreciation and care for vintage instruments. Above and beyond service on my Burns Jazz Bass. I used to go to local Music store for drop off and wait for weeks luthier service. They stopped offering that service and recommended Balboa Guitars. I’m glad they did.

★★★★★ — Hobie, Jun 2026

Mark is gifted at guitar repairs and will give you top quality work for a great price. He has written several amazing books on understanding the fretboard. I have been taking lessons weekly for over a year and I am inspired to practice daily!

★★★★★ — Matt, May 2019

I can't speak highly enough of Mark at Balboa Guitars. I had him install a new bone nut and saddle in my Gibson J-15 acoustic and the work is beautiful. He's a really genuine guy and took the time to discuss the work and answer all my questions. I'll be back soon with more guitars for him to work on. Great shop!

Lessons at Balboa Guitars

Reviews and the store's own info mention lessons at Balboa Guitars. If you're signing up a beginner (or restarting yourself), a quick call ahead answers the three things that matter: which instruments they teach, whether the schedule has openings at the time you actually need, and what a first lesson costs. There's no wrong first guitar — a good teacher will happily work with whatever you walk in with, and a shop that teaches usually keeps affordable starter instruments on hand for exactly this reason.
