Markbass Super Booster features: Clean Volume Boost Vintage Loudspeaker Emulator Filter Variable Preshape Filter True Bypass Circuitry Built-In Active DI With Ground Lift I have barely used this pedal and don't really need it. Pedal is super clean and comes with power adapter. This pedal always sat on top of my amp rack and never on the floor (when used) to get banged around as you can tell by the picture. If you're familiar with Markbass you know what these filters can do and how much they can help enhance your tone. Volume boost plus the DI makes it that much better. Will have the pedal in its original box. Thanks for looking. Asking $80 shipped in the U.S. Paypal accepted.
