version has a blue button. Chorus guitar pedal The last SR&D brochure featured a Rockman Stereo Chorus pedal in the same style as the AGP and the Ultimatum. The only controls on the unit were rate and depth. Like many SR&D products it is likely that this existed only as a prototype awaiting a market-driven response. It is unknown if this unit was ever produced or just existed as a graphic on the final brochure. Dunlop Releases The Rockman designed and sold by SR&D has since been discontinued. Only the Ace family has remained in production and is currently sold by Dunlop. Guitar Ace ($89.99) Bass Ace ($89.99) Metal Ace ($89.99) Notable Albums recorded with SR&D products Although it was marketed as a portable headphone amplifier, the Rockman also allowed the guitarist to plug directly into the mixer on the stage or in the studio. This effectively made the Rockman a DI unit for many guitarists.
