Hi, anybody tried these Stageworks non-slip pedal mats ? : http://www.stageworksgear.com/products/non-slip-pedal-mats-guitar-keyboard-drum-effect.htm I have a Roland TD-4K e-drumkit in my room (hardwood floor), and whenever i hit the kick pedal (or the hihat pedal for that matter), the kick pedal and the kick pad keep getting pushed further away. Right now i put them on top of a folded (approx. 5 layers instead of one) bathroom carpet (mat ?) (note : they have their own separate carpets so far : one for the kick pedal+kick front, and one for the kick rear part) so that they don't sit directly on my hardwood and don't damage it. I know the best solution is to have an entire carpet/rug/mat on which the entire drumkit sits, including the drum throne, so that everything stays in place when i hit the pedals, but i'm lacking space in my room and i'd like to give those non-slip pedal mats a try. Some feedback about those would be cool !
