Balboa Guitars Musical Instrument Repair: $70 Guitar Setups

Balboa Guitars, at 3942 Balboa Street between 40th and 41st Avenues, is a one-man guitar shop in the Outer Richmond where Mark Newstetter repairs acoustic guitars, electric guitars and basses by appointment only. Every job carries a $30 minimum bench fee, and a full setup on a steel-string acoustic costs $70 plus strings. For musical instrument repair a few blocks from Ocean Beach, this is the bench where the person who answers the phone is the person who holds the screwdriver.

Newstetter grew up on New York's Lower East Side and has lived in San Francisco since 1981, playing guitar and bass in rock bands, folk groups and behind jazz singers. His bio says he learned repair by fixing his own instruments, drawing on skills from his father, an aeronautical engineer, and from art school. He built instruments in the 1980s, including a 1987 piece called Nazanin for a Persian musician, but says he no longer builds. He opened Balboa Guitars in 2009 and has done repairs steadily since, alongside about 25 lessons a week.

The repair page lists rates line by line, which makes this one of the easier shops in the city to budget for. Prices are based roughly on a $100 hourly rate, and parts are always extra. A restring is $50 on a steel-string acoustic and $55 on nylon; a four-string bass is $45. Twelve-string guitars add $30 to the listed restring and setup prices. Intonation on an electric with a fixed bridge or vibrato is $25, and $40 on a locking bridge.

All setups include a restring, action adjustment, cleaning and polishing frets and fretboard, lubricating moving parts, tightening loose hardware and an inspection with advice. The price changes with the hardware. A Gibson-style fixed bridge is $70, a Fender-style fixed bridge is $75, and a Fender-style tremolo is $85 because the spring tension has to be balanced. A Floyd Rose or other locking system is $95, and the page explains why: some steps have to be repeated before the mechanism stays stable. Four- and five-string basses are $70.

The bigger structural jobs are where a small shop like this earns its keep. Re-attaching a lifting acoustic bridge costs $150 to $250, and the page walks through the process: the bridge comes off completely, old glue and splinters are cleaned away, and the bottom is shaped to match the curve of a top that has bellied over time. An acoustic body crack up to three inches is $75, with larger cracks quoted on inspection. A new bone or Tusq nut is $140, a saddle is $80, and the pair together is $190.

Fret leveling is $225 plus strings, and it covers removing grooves, recrowning, polishing and conditioning the fretboard. A full refret is $400 in labor on an unbound neck and $500 on a bound one, with fret wire added; stainless steel frets add $1 per fret. Electronics are priced just as plainly. Replacing an input jack is $40 plus the part, and a standard under-saddle pickup in an acoustic-electric is $100, including drilling the bridge for wiring and a hole for the jack. Pickup swaps get a $10 discount when combined with a setup.

Newstetter is clear about the limits. The shop offers touch-up around repairs but no complete refinishing, so a guitar that needs a new finish should go elsewhere. Same-day service is not guaranteed. The FAQ says a job may take anywhere from a few days to a few weeks depending on the queue, and that he would rather under-promise and over-deliver. Rush work happens only when the workload allows, so a broken guitar on the morning of a gig is a gamble here.

Repairs are booked through a request form on the repair page, and he asks for the type of guitar, what needs fixing and when you need it back. There are no published walk-in hours, so do not simply turn up on Balboa Street. The FAQ has one rule that surprises people: leave the strings on. Even with a broken neck or a separating bridge, he asks you to loosen the strings rather than remove them, because a guitar without strings is harder to diagnose.

The customers are mostly local players. Some are his own lesson students, since he has given an estimated 20,000 one-on-one lessons over the years. Others are working musicians who need a Telecaster fixed between gigs. An hour-long lesson costs $65 in person or online, and the shop sells a Fretography book that maps chord and scale shapes across the fretboard. The same instincts show in the repair FAQ, which explains neck relief and string buzz in plain language.

The FAQ also contains the most useful bit of candour on the site. Solid-body electrics are set roughly 30 percent lower than acoustics, so they will rattle when played hard without an amp, and no setup can prevent that. Newstetter also points out that some buzz comes from technique, such as fretting too far from the fret wire. If your complaint is a faint unplugged rattle on an electric, skip the setup and save the $70; if the buzz is loud through the amp, book the visit.

The shop sits in the quiet western stretch of Balboa Street. Walk east and you reach the Balboa Theatre, a historic two-screen neighborhood cinema. Head west instead and the street ends near Sutro Heights Park, the old Adolph Sutro estate gardens on the bluff above Ocean Beach, with views over Seal Rocks and the Pacific. Leaving the guitar for a week gives you a reason to come back for the walk.
