Reese Bass

Named after the 1988 Detroit techno track Reese by Kevin Saunderson, a Reese bass layers two or more sawtooth oscillators detuned against one another so their phases drift, producing a metallic, animated growl that became a staple of drum and bass, dubstep, and neurofunk. That same detuning makes the sound heavily stereo and therefore prone to phase cancellation, so a Reese needs care: keep the low fundamental in mono while letting the upper harmonics spread wide, then shape the growl further with filters, distortion, and modulation. Producers often split the patch into a clean mono sub plus a widened, processed top layer, so it stays powerful on mono systems while still sounding huge in stereo.
