Just how small can a drumkit be and still be decently flexible for a variety of styles in rock, metal and progressive jazz-metal-fusion? I find it hard to imagine a kit with much less than bass drum, snare, kick, 2-3 toms, hi-hat and at least three cymbals. And yet, I see youtube vids where the drummer is using mostly bass drum, snare, kick, just one tom, hi-hat used as a dead cymbal and mostly two more cymbals; the rest only sees occasional use - however, it's this occasional use I'd be worried about not having. But it still makes me think such a compact kit, combined with a hex or octal electronic pad which could be programmed for a variety of things on a per-style usage, just might do the trick. BTW, are there any double-pedal electronic bass drums capable of emulating two different bass drums?
