How does a double bass drum work?
A double bass drum pedal operates much the same way only with a second footplate controlling a second beater on the same drum. Most commonly this is attached by a shaft to a remote beater mechanism alongside the primary pedal mechanism.
Should I get a double bass drum pedal?
Double pedal technique requires a big investment of time to master, If you are a session musician you will possibly use it, but If its not something you require for the music you play then the time could be better used perfecting the style of drumming you like and use. If its something you want to get into then do it.
Should I learn double bass?
Absolutely. Even if you hardly use it (I for one prefer metal drummers that aren’t reliant on it) it’s worth the effort to train you’re left foot. Yea I hardly play double bass. I don’t know how double bass can translate well to funk drumming which is what I play as well.
