This kit is up for sale in Stockholm. This is the first time I've seen mounted paper clips used to attach a wrench to the bass drum. It seems handy though. There are some other clips mounted to the drum, I have no idea what they are for.

What unusual stuff have you seen mounted to a bass drum?

I have NEVER seen so much crap attached to a drum before! Maybe they like to look at drawings by their children while they play…
