A mounted tambourine, a small cowbell mounted on the same rod as my tambourine, a large cowbell mounted on the kick batter hoop and plus a 10" splash, is must have, standard equipment on my kit. I find that with those extra things, I can handle most styles of music, so they are as much a part of my kit as my snare. In use them quite a bit, they really add a refreshing sonic dimension. They are fun to play and hear. Nothing defines the QNP like a cowbell too.
