I asked this about the 300 watt BASH amp in another thread, but this one is much more appropriate.
Is this subsonic filter the same thing as the stock settings as listed on the boost sheet
(G=+1dB, Fc=17.7Hz, Q=1)? I do understand that a bass boost will make the low end roll off faster which I assume acts as a rumble filter. Am I way off base here or is there some other mechanism in the amp at work?
