Gibson added the center block to reduce feedback as players were cranking it up on stage. Gibson 330 is quite similar to the Casino, but for some reason was not as popular.
The Epiphone Casino is a full hollow body guitar that has no center block of wood inside like the Gibson 335 has. The pickups sound amazing with all of the bite and snarl that you would expect from P90’s. I even added a black grommet under the 3-way switch like John had on his. This guitar looks and feels GREAT, resonates better (it just doesn’t look like it was dipped in plastic anymore). I removed the ugly white pickguard and put it way. Also the obnoxiously thick factory coat of Poly has been finely sanded down to a satin/matte finish (except on the headstock). Modifications to the guitar that made it a better player (just like John Lennon did) was to change to Gold Grover tuners and now stays in tune better.
The Peerless Casinos have gained the reputation of being the better Casinos. Very cool John Lennon inspired Epiphone Natural Casino MIK in 2002 by Peerless.
