Getting ready to replace the fingerboard on a 1965 Kay. I have a symmetrical fingerboard available but I may want to put guts on it one day since it seems as if I haven't lived a full life (according to some posts in the string forum) if I haven't owned a bass with gut strings. Frankly, I never owned or played guts, but I have heard the sound and it is intoxicating. Is it mandatory to have a Romberg bevel? My understanding is that the sole reason for the bevel was the large diameter of the E string.
