eh? why would having an extra fader mean you can do more chops with the channel faders?
the only reason to buy a 3 channel mixer is if you're going to be using 3 channels
i know it doesnt make sense
but i like a bit of space between the up faders and two channel mixers are two clsoer togther unless you get soemthing like a hak 360 (a mate of mine has one of these - and imo best mixer, for that kind of thing)
