Ashdown Drive Plus Why should guitar players have all the fun, Ashdown's Bass Drive Plus pedal generates a wide range of bass distortion effects from a slight grunge through to no holds barred, high-gain overdrive. The Drive control sets the amount of distortion, Distortion Tone adjusts its character and Distortion Level balances the amount of the effect with the clean bass signal. The pedal is housed in a durable metal case and features an input level control with a trademark illuminated Ashdown VU meter to allow optimum signal matching from any instrument - active or passive. The pedal also features an output level control - essential for obtaining the perfect balance between the effect and the true bypass mode.
