This is a high fidelity recording. Transfer from master tape to master lacquers is made on Ampex 300 Tape Recorder, Scully Variable Pitch Lathe and Grampion Feedback cutterhead. The variable pitch control of the Scully widens the groovews for loud passages and narrows them during quieter sections, forming the light and dark patterns that can be seen on the surfaces of the pressing. The finest vinylite compound is used. For best results, observe the R.I.A.A. high frequency roll-off characteristic with a 500 cycle crossover.
