For some of my recordings, I use a drum machine (BOSS DR770) which has good effects (verbs, gates, etc....) built in, but I prefer to have the actual drum machine DRY when recording. I use a NanoVerb as a dedicated drum machine effects box just on mixdown where I can dial in just the right amount of verb on the overall kit, giving my drum mix a real and live sound - hear for yourselves at www.davevance.net
