Experience a world of sonic possibilities with three different types of drive engines. Choose between a Deep low-end fuzzy drive or a more gnarly overdrive with Normal selected. The Thin position adds tightness and presence. 

The new Blend control lets you precisely determine the perfect balance between your clean signal and the gripping drive. We’ve included a convenient Gain adjustment pot inside the pedal, ensuring you can compensate for the volume if you experience a drop in level at your desired mix setting.

Billy Sheehan Signature Drive

THE EBS OCTABASS BLUE LABEL PUSHES THE BOUNDARIES FOR WHAT HAS BEEN SEEN AS POSSIBLE WITH AN ANALOG OCTAVE EFFECT. THE QUALITY AND CHARACTER OF THE OCTAVE TONE, AS WELL AS THE PRECISION AND SPEED OF THE TRACKING, ARE OUTSTANDING.   
The EBS OctaBass was the first effect unit ever made by EBS. It is famous for fast and accurate tracking and a fat, natural sound. When you play your instrument, it "tracks" the note you play and produce a sound one octave below to mix in with the note you play.  The 'Blue Label' model has a couple of new features that enhance the tracking range and improves the control of the sound.

UniChorus Studio Edition, Rev 2

THE EBS STANLEY CLARKE SIGNATURE WAH/TONE FILTER IS MUCH MORE THAN A STANDARD WAH PEDAL. IN FACT, THE MAIN IDEA BEHIND IT WAS TO SIMPLY USE IT AS A TONE FILTER TO BE ABLE TO RE-CREATE THE SOUND OF STANLEY CLARKE WITH A STANDARD PASSIVE BASS. AND OH, DID WE MENTION IT CAN BE USED AS A VOLUME PEDAL TOO?!
