Am building a Big Muff Pi and am a bit unsure which variant to go for. Several have changes to prevent the mid scoop of standard BMPs, which sounds good, but apart from that I have no idea which would best suit bass. No low roll off is obviously crucial, with fuzz giving apparent bass roll off anyway I don't want actual loss of my lows. Anyone any thoughts? I know people here like the Fuzzrocious version of this classic.
