Ben l'action se mesure du haut de la frette au dessous de la corde sinon la mesure n'a aucun intérêt, rapport au type de frette (basse et plate, haute et fine etc...)
“The type of cap is not as important as the value of the cap, for guitar. In an Amp, your cap type is much more important, as the signal is being passed through the cap all the time. In a guitar, you’re not hearing the cap itself, you’re hearing what the cap is impeding”. Lindy Fralin
