Re: Unreliable heads, edges, or drummer?
If you still have the original heads, throw one on it to see if it's easier to tune and stays in tune. The new Mars kits should have a bearing edge (Sonic Clear) that sits more to the inside of the shell. The heads should sit flat on the edges and thus should be VERY easy to tune. If you have the same issues with ALL the toms, chances are it's not the drums but the heads.

Play the SONG......not the DRUMS!!!
"I think that feeling is a lot more important than technique. It's all very well doing a triple paradiddle - but who's going to know you've done it? If you play technically you sound like everybody else. It's being original that counts." ~ John Bonham
