DESCRIPTION:
This is a drumshell resonance comparison of current production Ludwig Supraphonic LM402 (the "Bonzo" model) with and without the rubber gaskets under lugs. Ludwig has added the gaskets for few years on new Supraphonics and Black Beautys, which IMO may be one of the reasons people complaining of the new models not having quite the same sonic qualities compared to the old ones.
