Bass Overdrive Info:The MXR Bass Overdrive is an original design that delivers warm, tube-like overdrive. Along with standard Volume, Tone and Drive controls, this pedal features a Clean control so you can blend a pre-set EQ clean signal with the overdrive signal, resulting in sweet burly bass overdrive. ""Punch your bass into the mix with the help of the MXR Bass Overdrive." - Juan Alderete, Racer X / The Mars Volta
