Overview:

The new Amptweaker TightMetal™ distortion pedal takes the TightDrive™ and TightBoost™ overdrive platform to the next level by providing over-the-top metal and hardcore crunch tones with adjustable tightness thanks to the Tight control.

•  This issue came up early on when discussing various ideas with Mark Kloeppel, guitarist from the deathgrind band Misery Index
•  Like many other metal players, Mark was looking for a particular guitar tone, one with a lot of harmonics but with the ability to stop the notes really fast to work with their music.
• As on the original TightDrive, the Tight control varies the low end from smooth and thick to tight and aggressive so you get the attack that works with your guitar and picking style.

• In the same way high gain tube amps are designed by cascading extra tube stages, 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, so it’s easy to get a stack sound even through a small combo amp’s clean channel.
• At January NAMM '11, various metal players made suggestions about adjustments to the gate, and the result was a redesign to include an automatic gate threshold that tracks the gain control......this keeps the Chomp setting appropriately hard, and backs off on that setting as the gain is reduced.
• All other features from the TightDrive remain intact, including the Effects Loop with its Pre/Post switch, the LED illumination of the controls, and the Battery On/Off switch and magnetic battery access door.  The effects loop send can be used as a clean guitar send for re-amping in the studio if switched to Pre.
