Today I removed all the frets from this EKO guitar n. 100, vintage semi acoustic from the 70s, Italian factory production (Recanati).
Removing the frets is usually a necessary operation on all vintage guitars, which have not had special care over time.
The frets needed to be changed with the use of the guitar, being composed of relatively soft metal material (18% nickel). Only a few recent models mount hard stainless steel frets, which last longer, but unfortunately make various complications during their mounting on fretboard.
When only the first frets getting used, it often means that the instrument played with a wrong setup.
