The EBS Billy Sheehan Ultimate Signature Drive pedal is a distillate of several important principles in the signal chain for bass, providing compression, distortion, tone-shaping, and blending all together.

Specifications

• Splits the signal into two parallel paths, one clean and one with distortion, providing a sound like running through two different bass rigs at the same time
• Phase Inverter switch brings back more low-end to the drive channel in cases when phase cancellation appears
  
• Hi or Lo Frequency Filter switch moves the whole frequency spectrum of the Tone filter up or down to extend the capabilities of the pedal
