El Calibre™ — Luthier’s Gauge Tray
El Calibre™ is a precision tray designed specifically for the gauges and fine reference tools used in guitar setup and inspection.
In lutherie, accuracy depends on visibility and order. Feeler gauges, string action references, nut slot gauges, and setup tools are used repeatedly and in sequence. El Calibre™ keeps these tools upright, separated, and immediately readable, reducing handling time and preventing damage to thin, delicate edges.
Machined from Baltic birch plywood and finished for durability, the tray uses elongated slots and calibrated spacing to maintain consistent orientation and spacing between tools. Each gauge is easy to remove, easy to return, and easy to verify at a glance.
El Calibre™ is designed to integrate naturally with the CUSTOMadera Luthier’s Tool Caddy, or to stand alone on the bench as a dedicated setup station.
This is not general storage.
It is a reference surface — built for clarity, consistency, and trust.
