A man after my own heart.
I've got one of those old LP's. It's long and heavy, about a half and half mix of black paint and rust. Thing's a sound beast.My #1 is an LP from the 70's, and I think what sets it apart from the newer ones isn't some mystical vintage mojo but the fact its sheet metal is much thicker than modern LP bells. One of my other top faves, a "Striker" (their last inventory was sold here on the forum a couple years ago) is also thicker sheet metal. I also love JCR, I have a few, and their sheet isn't necessarily thick but it has a really resonant quality. So these are not useful recommendations exactly, BUT if you keep an eye out for bells that have more thickness and heft, or steel that doesn't sound thin or "cheap" (in the quality sense), you will be on the right track.
