I love these triggers. I bought 2 singles and 2 duals. They have transformed my DW Frequent Flyer into a flexible and noise-sensitive, hybrid beast. The set up includes silent stroke heads, low volume cymbals and a Roland module. I love being able to switch from analog to digital depending on my sonic mood. And my townhouse neighbors enjoy not hearing me rock the casbah - ever. Sam Ash also gave me a great price and their usual wise counsel.
