Re: What to look for when buying used pedals...
For the most part, if bass drum pedals look okay, they probably are. It's pretty hard to damage bass drum pedals, even the cheapsters. Bass drum pedals today are made extremely durable. I'd make sure the cams aren't cracked or anything. Make sure the chain . strap is good shape. Make sure no bolts are missing.
I've honestly never heard of anyone just breaking a pedal outright. I've had a few come loose from a lack of tightening the proper areas, but never broken one.
