Shreddage is known for its low-end weight. When converted to a Soundfont, that low end often gets tightened up and slightly distorted by the sampler's pitch-shifting algorithm. The result? A chug that sounds like it was sampled from an old breakbeat record. It cuts through a mix with a sawtooth-like aggression that a clean VST simply cannot achieve. Think early Nu-Metal meets J Dilla.
