These triggers work just great on my Yamaha kit that I use in the studio, I have never seen another thing like it. I run a 300 watt power amp to push a 5 15 bass bottomm plus the sound from the accustic drums the rest of the boys have no problem feeling the drums. These suckers are as we use to say "Far Out Man"

I put these on my acoustic set pluged them in to my TD8 roland controller and they work great. No extra muffling needed. My drums sound huge and are a blast to play.

I've been running these triggers with an Alesis DM5 Module. I've always tuned my toms with no muffling for a wide open sound, a zero ring on my snare if needed (depending on the room) and a PowerStroke III bass drum head, with a bath towel for muffling. I had a few issues with double triggering when I first set these up, but after getting comfortable with them..I was able to tweak them without a problem! No additional muffling needed at all...and the best thing is that I can still hear the great acoustic sound out of my drums from behind the set! I'd recommend these to anyone, without hesitation!

Great Triggers! little if any false trigger. The only problem I have had is the bass drum doesn't always keep up on double bass patterns.

I actually bought a used set of these triggers from a local store. I use an Alesis DM4 module. There are some problems with double triggering, but it's not too bad. You just need to make sure you muffle the drum head with some duct tape or something. That will eliminate the head pulsating and causing a possible double trigger. These are overall a great deal. I use them for recording and live. I haven't tried anything else, but my friend has the step up ddrum triggers, and I don't notice much of a difference, so I don't know why someone would pay the extra.
