I recently picked up a Ludwig Coliseum with the intention to sell it to someone that may get more use from it than I would be able to give it.
I noticed that there is a perfectly square cut out on the angle below where the bearing edge makes contact with the head. If you flp the drum over there is one on the exact opposite side of the drum from the top and in the same spot on the angle.
At first glance I thought it may have been ply separation but the angles are too perfect, but I suspect that it may have actually been part of the shell manufacturing process. I am guessing that the cut out was part of the mold of the shell itself. The square looks like it less than 1/8" (or 2 ply's I guess), maybe 1/16".
I tried to snap some pictures, but the head reflects the flash and you can;t really see it.
Can anyone confirm or provide insight on it?
The drum sounds fantastic BTW.
Thanks!
