Supraphonic w/ Internal Muffling?
When did Ludwig stopping putting internal muffling on the LM400? I’m in the market for a used Supraphonic and the pictures of one from the 70s (based on having the Ludwig “pointy” badge) show an internal muffler. Good/bad? I like having an internal muffler, but Ludwig must have had some reason for removing it, unless it was just an expense-saving move. I suppose that it’s possible that the internal muffler was added, but I’m not brave enough to drill into a metal shell.
