Well the alpine website says the knob is sold separate so I assume it doesn't, I'll just buy the PAC. A concern I had about the Alpine knob is that it would override the amp's gain settings and so setting the amp gain would do nothing and the knob would do all the controlling, thus leaving the potential of accidentally turn the bass knob up and clipping my signal...As in the amps settings wouldn't matter... so turning the knob to full would be like turning the amps gain to max... which has me spooked. So I think I'll stay with the PAC
