EBS ValveDrive Pro Dual Mode Tube Overdrive
Back in the early '90s, Tube Works introduced a preamp called the Blue Tube. It added tube warmth, compression and overdrive to any amplifier, and worked particularly well with electric bass. Though it has since been discontinued, EBS, a company founded by bass players for bass players, has filled the void with their ValveDrive Pro. This Class A tube preamp, like the defunct Blue Tube, infuses your bass with authentic tube warmth and compression, plus two different kinds of distortionvintage and modern, the latter having more high mids with less compression. The bass, mid and treble controls make this a fully functioning preamp, and a welcome addition to any pedal board.
