From the post
Info from the manufacturer:
The AMPEG Scrambler was designed in response to requests for a distortion device that was flexible, easy to use, and most importantly, musical. Inherent performance limitations of all designs on the market precluded one or more of the aforementioned requisites. New concepts and methods were researched and tested by leading musicians until every requirement was surpassed. The end result was enthusiasm on the part of every one who tried the unit.
Basic understanding of the unit and its operation will result in the ability to use each of the sounds that the unit can produce. Don’t be afraid to experiment with all of the controls – a little time spent with the Scrambler will enable you to use the unit to its fullest capacity.
