Has anyone ever used multiple ambs/cabs (via A/B switch, etc) for different tones in a live/practice situation? The first time I heard of this was probably Tim Commerford (RATM) using a few SVT rigs set at different levels of overdrive. My situation is that dialing in my favorite articulate metal tone (Mesa Bass 400 with a SABDDI in the FX loop... naturally a pretty direct and defined sounding head) leaves things almost too sharp on the higher ranges of the bass. It sounds killer and mixes perfectly when slapping on the B string or playing aggressively, but I often wish I could tone things down when tapping in higher octaves or get a big smooth sound (e.g. the type of tone I use in my hip hop project) without having to reconfigure everything. Maybe I am justifying a case of GAS but am curious if anyone has ever tried this. I'd love to have something like a Streamliner or a differently set 400 for awesome tapping tone to A/B with (or Y into both for some massive sound). My only regret on my last album was that my tapping came out harsher than intended (time/budget... I would have plugged into the studio SVP- for more forgiving tones if I had unlimited time to think about that stuff).
