Flintrock Guitar Shop

Flintrock Guitar Shop Repair of stringed instruments, amplifiers, vintage and pro audio. By appointment only, call or text. I can repair most stringed instruments. Many mods available.

I offer setups, electronics repair, minor fretwork, restorations, parts replacement, pickup changes, etc. I also make and repair tube amps. I can bias, mod, or restore almost any tube amplifier. I also launched Hawkins Effects Pedals and make a few of these every now and then. I am not the fastest tech around and not nearly the slowest, but I do get things back to you in a reasonable amount of tim

e. Occasionally my workload slows things down but I use the rule first in first out. One thing for certain and many people cant attest to this is that I am priced fair and I do dependable, quality work. I treat your gear like it was my own.

A couple more recaps going out the door! A mint condition Yamaha Fifty112. The Earth will be getting new k***s and had a channel out due to one little transistor. Ready to go another 20 years.

Cranked out another full recap and retube on a great sounding '77 JMP 2203. Previous tech really squeezed an effects loop in there!

Just a few things on the bench! A lot to get to this week when parts orders roll in Mon/Tue. Due to the amount of parts ordering happening pretty much all of the time now, the bench fee will now be due at time of drop off. I don't always enforce the rule but now I have no choice. Almost all shops do this all the time. 1990 Mexico strat is for sale, hit me up if your interested. Only 5 gigs for me this month lol, so I may take a wee bit longer on repairs, but your always in good hands here at Flintrock. Have a great week and rock on!

Happy Sunday musicians! Boy have I slacked lately taking pics of the gear I've worked on. It has been busy! Here's an old Peavey Mark III that was in for one of my favorite local bands, replaced a voltage regulator that failed and it's back in business.

Nitty Gritty boost/transparent drive pedal. I have only 2 left of the last batch. 9V DC power adapter needed, no battery option in these. $95 each and I'll fix it if it ever breaks.
