The goal of Groove Bias was to create a set of deeply sampled acoustic drum kits inspired by classic 50s, 60s and 70s records and the timeless breakbeats we all know and love. For decades, these sounds have been imitated and sampled over and over, but many producers have preferred to try and capture old kits with pristine, modern recording methods. Not so with this library. Our motto was “the more tubes, the better,” and we armed ourselves to the teeth with beat-up mics, analog gear, vintage drums and tape machines.

We put over eight months of work into the meticulous recording and editing process, whole sessions going by before we were finally satisfied with a single snare sound. The result is what we think you’ll agree is the funkiest, “phattest” acoustic drum library around. We hope you enjoy Groove Bias!
