I play e-kits at some rehearsal spaces. They are good for low-volume rehearsing and I especially like them because they keep me from having to bring anything to rehearsal but sticks and a few beers. I have played e-kits at several churches and once again, I was happy to not have to bring my gear, but I still prefer acoustic sets for live performances. There were times that I hit multiple instruments at once, like a bass drum and cymbal, and one or the other sound wouldn't show up in the system. Not good when you stick a big BD hit on 1 and it's not there. Also, you are at the total mercy of the sound booth and I've had people come up to me after services and tell me that they heard more of the sound of the stick hitting the pads than they did of the electronically generated sounds. Limited dynamic range may be attainable on e-drums, but nowhere near the sensitivity and range that acoustic drums provide. I won't even mention cymbal sound quality because it is not even worth my time to type it. Y'all know what's up.
