Yes, I can guarantee they have been neglected. I agree with the rust comments, and I'm sure they haven't been taken care of lately.
I'm assuming based on the comments to stick with the Imperialstars for now, even though it costs more, and only has a 18" bass (what Tama calls the "compact" set). The biggest advantage of that set is that they are pretty much brand new, just been sitting in someone's house with a lack of use. They run about $650 new online, so they seem like a pretty good deal. I was just curious if any of you experts saw a problem with a compact set. I'm sure the drums won't sound as impressive as a full size set, but I'm sure they'll still sound pretty cool to a 10 year old. Maybe if he sticks with it, we can upgrade to a nicer set in the future, and I'll be BACK for advice. I'm just trying to stay away from the low end new set of "Percussion Plus" drums for $300 - $400, where you can literally bend the cymbals with your fingers (really easily)!!!
Thanks for all the comments, guys. I really appreciate it. Let me know if you have any final thoughts.
