When we went into the studio this summer, the engineer was having a bit of trouble getting the right sound out of the kick. For whatever reason, this *ever so slight* overtone from the reso head was being picked up by every kick mic he threw in there. The kick sounded awesome in the room, but it just didn't work with the mic. When he'd aim it away from the reso, he'd lose the annoying overtone, but he'd also lose the OOMPH of the kick. Very strange... this was never an issue when miking live...
He was getting ready to pull the reso head off of the drum, but I just grabbed a 15" floor monitor, set it on end in front of the kick, and ran a 1/4" cable into a DI box. Told him to try that. Voila! The oomph was back, and we were able to continue on our day. We had a gig that night, and I didn't want our drummer stressing about messing with the head.
PS - later, he found out the problem (don't recall what it was right now), and pulled the monitor away from the kick, saying he was getting what he wanted from his mic and didn't need to use the speaker.
