For me it was the Make Noise 0-Coast [1], which has many of the West Coast sensibilities. The Neutron (which you'll see I've reskinned in my setup) is a great synth, but is still more of a 'standard' subtractive (East Coast) synth. Although it does have some interesting wave shapes and can produce lots of filthy tones.
