Efrén Gorrostieta Hurtado is a real renaissance man.
A guitarist as well as an engineer, professor as well as researcher.
When he got his new guitar he wrote me
estoy muy feliz con ella me gusta mucho
tiene un lindo timbre y una buena proyeccion.
y muchas gracias por esta guitarra tan linda que me fabricaste.
That’s nice to hear when you are a guitar maker.
