I'm using this Gibraltar clamp to expand my Roland Octapad to expansion triggers.
So I got the Roland tripod PDS-10 Pad Stand, there I attached this Gibraltar clamp, to which one I attached the Millenium DB-115 Cymbal boom arm, to which one I attached the Millenium MPS-300 Mono Cymbal. And so the reason why I chose this clamp is because it offers the possibility to play with different inclination and angles, inclination gives you more reaching distance and that's the advantage of this clamp, the cymbal boom arm doesn't need to be straight, it can be inclined and provides more distance, which I need for my Mono Cymbal MPS-300 which I use as electronic Hi-Hat at a descent distance away from the Roland Octapad so that it will not disturb my drumsticks traveling from the Hi-Hat or the Snare Drum to the Octapad.
I'm glad to have this product, and why I chose this clamp over a traditional cymbal stand, because I wanted to have as less stand legs as possible so it makes it easier for pedals and for cleaning the floor ))
Cons - A bit overpriced, but as long as I have no complaints regarding quality then it's fine.
