If something`s really wrong, be sure to get a mom or dad for this one, I like restoring old tamas.after you`ve tried the above tips and they don`t work *and only if they don`t work* feel free w/switching out the innercomponets for working ones. mabye you painted on eand don`t like how it`s worn off over time? the innercomponets from an inside of a tama can help it look spiffy.however the sound will be destroyed...so remember that too...
