We've been using a modified stock RB2 wireless kit for years, mesh heads, metal reinforced frame with the "Rock Pedal" which is still solid and works great. Wouldn't change a thing, except that our drummer has now outgrown having just one pedal and wants to try having a second one. I can't find another Rock Pedal online (and I don't think I would want another one anyways, they are too bulky).
I'm strongly considering this one from Yamaha. $65 with tax.
I'm not sure how sturdy that thing is but the price is right.
What do you guys use or recommend ? I find that if you're not looking for guitars or mics, drum accessories are increasingly hard to find online.
