SFX-05 Lava Box

The Lava Box is not an ordinary Mosfet distortion/overdrive effect pedal. It actually reacts more like a great amp than a stompbox, with the depth and dynamics that give well-made amps so much character. When you think about the tones that defined so many of the true guitar heroes throughout history, they all really speak. They cut through. They say something. A huge part of that is in the rich midrange frequencies that the amplifiers of the day naturally produced. And, because those amps were typically cranked up to full volume, they were also incredibly dynamic, responding to different picking attacks and even subtle changes to the guitar's volume control.
