Boss DN2 Dyna Drive Pedal
Using the Dyna Amp technology taken straight from Rolands Cube-60 the DN-2 pedal lets you create unique tone transitions based on picking dynamics. Simply applying harder picking this pedal allows dynamic transition between clean to heavy overdrive.
Dynamic
This pedal senses the rate of attack applied with your picking and adds overdrive accordingly. When you pick softly it gives you a smooth clean tone, then a slow transition to heavy overdrive is applied the harder you pick.
