Because our drummer uses an electronic kit, we'll definitely need to hear that. We don't need to feel the kick, but need to hear enough to lock in.

With electronic drums I give the drummer a Roland KC150 4 channel keyboard amp as a side-fill.
Mono drums into channel 2 with it's own gain, line out out to desk.
Aux 1 from desk back to channel 4 the monitor channel, with it's own gain = foldback, vox and guitar. This does not go to line out.
So, the drummer has control over his mix of drums and his foldback and an overall on stage volume control. Everyone on stage can hear the drums. If the drummer has a mic he gets his vox in aux 1.
Just one solution that I find works very well.
One point, once the drum level is set on the desk the drummer must not alter the channel 2 gain on the KC150. He can only alter the channel 4 gain or the overall gain to adjust mid-set.
