Why this exists

GuitarTechHub is a guitar-and-tech site: precision calculators for guitar building and repair, practice tools, honest UK/EU supplier reviews, and write-ups of the actual software work behind all of it. It isn't a build log — I'm a software developer, not a luthier, and the site doesn't pretend otherwise.

The calculators exist because most luthiers currently work out fret slot positions, saddle compensation, string tension, and fretboard radius/relief from homemade spreadsheets shared on forums, for lack of a clean, purpose-built tool. Every calculator here prints a workshop-ready reference sheet, because a laptop isn't always within reach at the workbench.

The Code section is where the tech side lives properly: real notes on building this site's tools — libraries evaluated, bugs found, decisions made — written up honestly as they actually happened, not polished after the fact.

The AI-native backing track generator and metronome are for practice — jazz and blues progressions by ear, in any style. The backing-track generator specifically is an experimental addition; existing tools already solve a lot of that problem well, so it's being built and judged honestly rather than assumed to be an improvement from day one.
