These clamps are a brilliant idea for getting rid of a jungle of mic stands around the drums but they are not flawless. if you use SM57 microphones with a common holder they tend to cover quite a lot of especially small toms. If you use smaller mic's it should be fine though. You will have to find the sweet spot to place them and you can only hope that it's the same spot for the best sound. Try it out if you have the opportunity, they might be better for you than for us.
