Depends on your expectations and experience tracking. If you use dynamics v. condensers by definition the sound will be different. Also the dynamics might need to be closer.

Thanks. Don't have a lot of experience, no. I've been reading about both techniques and plan to experiment today with placement, but I wasn't sure if, because they were dynamics, they wouldn't pick up enough of the kit with any clarity.

Dynamics tend to be best on close sources. If you have a third mic I'd go kick, snare, single overhead rather than Glyn Johns or Recorderman if I was going with just dynamics. Not the greatest stereo image, but it can get a good sound.

If you have a competent mic pre a dynamic will do fine in this application. I am not sure what an M-308 is but I am guessing it is a lower end live board. This may cause some problems for you.
