This bass features a thick "Reese" style foundation with two sawtooth oscillators detuned by about 8 cents, layered with a sub sine wave at 43.65 Hz for deep low end. White noise adds grit before the signal passes through a time-varying low-pass filter that crossfades between a dark 250 Hz cutoff and a bright 5000 Hz cutoff, modulated by a rhythmic LFO cycling through rates from quarter to sixteenth notes at 140 BPM. The final sound is saturated with tanh distortion for harmonic richness and given stereo width via a 20 ms delay on the right channel.
It suits dubstep and heavy bass music around 140 BPM, where the classic wobble effect drives the groove. Use it as a prominent bass layer, possibly with additional sub bass or midrange elements for clarity. Watch for its gritty texture and strong filter movement to avoid masking vocals or lead instruments in the mix.
