Double bass drums or a double pedal are great for expanding your vocabulary on the drums.
Just don't get caught in the I WANNA PLAY DOUBLE BASS IN EVERY SONG TRAP.
As for the Jazzers ? Try playing dynamically a swiss-triplet with your feet under those swing feels to bring the swinging song to a roaring climax!
One of my students was playing in the school jazz band and the teacher said there was no need to bring his double pedal as it would not be needed for JAZZ. So he showed him the Swiss triplets I taught him and apllied this to an uptempo swing song and everybody smiled including the teacher.
Work on your rudiments with your feet just as you would your hands .
Virgil, Grant Collins, Mike Mangini, Marco Minnemann,and Thomas Lang are there demonstrating the endless possibilities with their feet.
So just see where you can take it.
But all of this takes patience, perserverance and PRACTICE!
Good Luck Tim Waterson aka The Drumcanman
