Hi, I’m Alvaro den Hartog
I’ve been building and repairing guitars since 2011. I co-founded Del-Tone Guitars, where I built the majority of the product line by hand — from rough timber to a finished, stage-ready instrument. That’s the standard every setup and repair on my bench gets held to.
Now I’m running a solo repair and tech practice out of Amsterdam — fast turnaround, honest communication, and the same attention to detail that went into every Del-Tone build.
Fender-style
Stratocaster, Telecaster, Jazzmaster — bolt-on necks, tremolos, single-coil circuits.
Gibson-style
Les Paul, SG, ES — set necks, tune-o-matic bridges, humbucker wiring.
How I work
Reliable and dependable — clear timelines, honest assessments, and a guitar that comes back exactly as promised.
Based in Amsterdam
Workshop drop-off, local mobile repairs, and touring/on-call support as it opens up.
