James Brown, designer of the Peavey 5150, owns and is the builder of Amptweaker stuff. This pedal was a joint project with him and one of the gutarists of Misery Index. According to James, it's kind of a mid point between a 5150 and an Ampeg VH-140C. This version just had a single tone control, but there were other controls to help offset the limiting nature of that design. Another cool feature was the output volume being able to sit at line level, so as to act as a preamp into an effects loop return or into a stand alone power amp. If you're a touring metal musician going overseas and using unfamiliar amps for backline, this may be your saving grace to have some semblance of a consistent tone through pretty much anything. Do recommend.
This pedal absolutely NAILS the 80's Thrash Metal sound. Anthrax's "Got the Time" is a perfect comparison. It'll also match Metallicas first four albums (five if you count Garage Days). And then most Nu Metal like Disturbed, Drowning Pool, and Slipknot can be matched with this. It's got it's own built in effects loop. I don't use it but it's a cool feature. I do find, however, that Korn, or bands with lower tuned guitars with more mids don't sound as good through this pedal as they do through a JCM or DSL. But that's just personal preference.
Description : The TightMetal was created by adding additional stages in front of a carefully modified TightDrive. The resulting thicker and much heavier distortion is tweaked by a simple built-in output EQ curve, and can further be adjusted by the output Tone control.
