Roland KD-A22 Kick Drum Convertor

We say:

Roland's KD-A22 kick drum convertor is an excellent way to convert your current 22" bass drum into a trigger for your V-Drums module. Please note that the KD-A22 package does not include a 22" bass drum or a bass drum pedal. 

Roland say: 

If you love the look and feel of your traditional acoustic bass drum, the Roland KD-A22 Kick Drum Converter lets you incorporate it into your V-Drums setup. This new trigger package fits to a standard 22-inch acoustic bass drum, giving you striking stage presence and acoustic-style feel thanks to Roland’s innovative air-damping mechanics working alongside the deep drum shell. The package includes everything you need to convert your 22-inch bass drum*—a front head, a batter head with a kick-pad sensor unit, a 22-inch metal hoop, and shock-absorbing cushions. The KD-A22 provides stable, consistent, and accurate triggering for your setup, and is fully compatible with double kick pedals.
