UniChorus Studio Edition, Rev 2

BassIQ

My new Deluxe pedal has more gain! It really screams. Much more than the first version, but you can always tone it down if you like. Also, one very unique feature that I think will appeal to a lot of people is the “swappable” 8 pin dual inline op amp. You can basically make it your own signature drive by replacing the main drive chip with another of your choice! Also, there’s a phase reverse switch for the drive channel that gives tones a very different dimension. And a “boost” switch to kick the drive into a much higher gain. All exciting new features that will make it easier for players to fine tune this device to their own personal needs

Billy Sheehan Signature Drive Deluxe

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?!
