Re: THE DRUM MODIFICATION THREAD.
The Renown line's shells are finished with silver sealer ( a Gretsch thing that improves the sound through resonance and sealing the pores of the wood). Other than that, the Catalina series lacks - A. Finished interiors on the shells and B. good heads. Heres what I did. I dis- assembled all the drums and sanded the interiors with 300 grit paper so that they were baby skin smooth. Then I sealed the interiors with Teak oil, applying several coats until the interiors were sealed and had a nice low sheen. The sealer, although not the silver paint ,that Gretsch uses on the Renown line, accomplished the same thing. That being, smooth sealed resonant interiors, that improve the sound. I then added Evans G2 over G1'heads and tuned them up.
I like the idea of sealing the interior with sealer or Teak Oil, what difference did you find in the sound, lower? warmer ?
