The A2-4 is a set of four, two-foot by one-foot ClearSonic panels. Designed for guitar speaker cabinets, the A2-4 allows a player to drive the amp and speaker to the level needed to reach the overdrive "sweet spot," without projecting all of the volume forward. Used with an S4-2, this system helps reduce stage volume and clean up stage sound without sacrificing your desired guitar tone.

ClearSonic panels systems feature full-length hinge, cable cut-outs, and a design that allows systems to fold "accordion style" for portability and ease of set-up.
