Schaller Lyra GD Acrylic

These tuning machines were a perfect match for my José Torres JTC-40 classical guitar, much better than the original ones. Installation was quick and straightforward, with an excellent fit that required only new holes for 6 out of 8 screws. Tuning is smooth, stable, and very precise, making fine adjustments effortless. The overall build quality feels solid and reliable. Highly recommended for anyone looking to upgrade or replace classical guitar tuners.
As an unexpected bonus, I found in the package, still wrapped in its original heat shrink and marked with the exact code for the acrylic keys, the version with ebony keys (and no, I'm not going to send them back for replacement :-))
