While we are discussing it, different strings make a HUGE difference. I had a pupil who had one with ******** strings on it. I honestly cannot remember what they were, but they were proper Arco classical strings and the warm tone could have solved the national heating crisis we are running into.
Sadly, DB strings are mind bendingly expensive so experimenting is very scary. NS stuff come with NS strings which are great for what they do but seem like long flatwound bass guitar strings. DB strings are made very differently.
