I am working on some ideas for a potential musical project which is likely to feature sequenced drums, plus live guitars and a bit of keys. Definitely guitar music but heavily influenced by bass-heavy dance music. For the bass I am looking at either - (1) Extreme sub-bass, potentially inaudible, using sub-octave pedal (POG 2, using 2 octaves down only?), sub-woofer and no cab producing mids, AND second bass doing a more orthodox bass role. or (2) Extreme sub-bass, potentially inaudible, using sub-octave pedal, sub-woofer, AND also running into a cab producing mids. In this case it is less likely that a second bass would be needed, but I'm still not writing a second bass off entirely. I have been looking into PA sub-woofers to use as a bass cab, trying to get my head around the technical side of things. Has anyone done anything similar? Did it go well? Any tips, suggestions etc?
