Drum tracking: Sound Secret No. 1 - Good and consistent tuning is key to a great sound

This is really important. There's a lot possible in mixing. But a snare that looses tuning during a song or sounds different on every song or even riff will most likely end up being sample replaced (which require additional fees) - and we don't want that (except it'll be a stylistical choice to have sample replacements).

A tune-bot and/or DrumDial is always a good investment.
