What You Need to Know AboutBearing Edges | Modern

Sharper bearing edges produce more attack and more sustain, which results in a generally more lively, “modern” sound. The added attack and sustain are due to less of the drumhead film being in contact with the shell. A sharp 45-degree edge also produces considerably more harmonic overtones, which makes the drum sound brighter.
