 Many players praise the Prosonic's clean channel as being "softer," and more prone to break-up and musically desirable distortion, than more contemporary Fender designs.Detractors view this trait as an apparent "darkness" in tone, and perceive this lack of the typical Fender "sparkle" as merely an undesirable lack of clean headroom.The Prosonic also brought levels of gain (distortion) previously unavailable in a Fender amplifier.
