About 2 months ago, I was hitting 200 bpm sixteenth notes with my feet. I was using the $100 pacific double pedal. I was just starting to get serious about double bass. Well my sessions came in along with my eliminators. Now I can't play steady sixteenths at all with any speed. I don't know what it is, I use the flatfoot technique. It could be I'm still not use to the new double pedal or not use to the bass drum which is 4 inches deeper than my old one. I don't know what to do, I'm really frustrated. If anyone has any suggestions for me I'd appreciate it.... Thanks, Cory.
