The Electro-Harmonix Knockout Pedal can give your tone the heavyweight punch it deserves. Two powerful filters are the key -- make your humbuckers sound like single coil pickups and your Strat sound like a Tele. Amazing on bass!

The Knockout Attack Equallizer lets you tweak the high-pass and low-pass filters, changing your sound from Gibson to Strat to Telecaster, with innumerable shades in between.
