Jim Dunlop are now shipping the MXR FullBore Metal Distortion pedal. Here's how they describe it in their own words...
Ultimate riff power is yours with the FullBore Metal Distortion pedal from MXR. This compact but powerful device is all you need to unleash the most devastating contemporary metal guitar tones ever heard. The FullBore pedal turbo-charges your guitar signal with lethal amounts of ultra high gain. This is combined with a built-in Noise Gate to knock out the noise associated with extreme gain levels while also adding definition and tightness to syncopated metal riffs.
Extensive EQ controls, with Bass, Mid, sweepable Mid-Freq and Treble knobs let you sculpt your tone with fiendish precision. The additional Scoop switch provides an instant high and low frequency boost that'll rumble the room while also adding clarity. Available from MXR, the world leader in analog pedal technology.
