Professional bass guitar repair, hot rod upgrades, and custom instrument building in the Phoenix metro. Every instrument gets the care it deserves.
Every service is performed by hand in our Phoenix workshop. No shortcuts. No assembly-line work. Your instrument gets the attention it deserves.
Full professional setup including neck relief, action, intonation, pickup height, nut slot check and lubrication, fretboard conditioning, and hardware tightening. Every setup includes a fret sprout inspection and dressing — dry Arizona air causes fret ends to protrude beyond the fretboard edge over time. Your bass will feel as good as it plays.

Kris has been playing music for 25 years. He studied music theory and performance in college and spent his career in sales — building something for someone else. Kaldera Guitars is built for him.
The interest in building started with furniture. It moved to guitars and basses because the craft connects directly to the music. Every instrument that comes through the shop gets a full evaluation, honest assessment, and meticulous work. Bass is the specialty — from $75 setups to boutique custom builds using exotic tonewoods and premium hardware.
The long term vision is original design. Not J bass copies. Not P bass copies. Instruments that are unmistakably their own — fine instruments that push the boundaries of what a bass can be.
