The EMG Afterburner (the name has nothing to do with the pleasure of Pepperoni, but is really hot) is equally suitable for active as well as passive pickups and offers an uncoloured boost, which can be continuously adjusted up to 20 dB boost. It is particularly interesting if you want to switch the distortion to the distorted lead sound simply from the guitar and to convert a good sounding but distorted tube amp to the Gainmonster without changing the basic characteristics of the Amp sound by distortion pedal.
