Amptweaker FatMetal Pro
All features are identical to the TightMetal Pro, but the tone has been tweaked to extend the low range of the Tight and Tone controls, and the Black Gain switch boosts the gain in an appropriate way to get the thicker, buzzier gain required for those genres.
The Thrash switch converts the basic tone into a heavier, more mid-scooped tone for classic vintage metal tones. The noise gate has also been retweaked to make it smoother, and to sound better with the reduced highs of the FatMetal to allow it to work better for solos....but it's internally adjustable if you want the TightMetal CHOMP gate, just crank it!
Amptweaker pedals are known for effects loops, and this one has 3: a universal loop, another active with the boost, and our popular SideTrak loop which activates when the pedal is OFF, to automatically shut off clean effects.
It can be used to add a compressor, chorus or chain of effects that only works when you play clean, or to switch to another distortion pedal to use for an alternate rhythm sound...all without having to hit more than one switch....it’s like having a built-in A/B box. A green LED alternates with the normal red one to indicate that the loop is active when the pedal is bypassed.
Another cool SideTrak trick is that if you only plug in the SideTrak Send, and don't plug in the Return, then that Sent dry signal can be sent to another amp.....meaning you could have the FatMetal Pro going through a 412 halfstack while sending the clean tone to a Twin or some other clean amp. All this ability comes from two simple jacks on the side of the pedal!
A question we get a lot is, can the boost work by itself? No, the boost only works when the pedal is ON….and here’s why: Since the boost has 2 boost knobs, one before the distortion and one after it. The gain boost is before and increases the distortion with only a little effect on the volume, while the Volume boost is after and increases the volume a lot. If the distortion circuit wasn't in between, then the volume would jump very high and result in a boost for clean that didn’t make sense. The boost footswitch also turns on the boost loop, switches in a Mid-boost switch and a fat-switch underneath, and is EQ’ed to work right with this pedal…..if you tried to use it as a clean boost, it would sound too mid-rangey for most people.
This setup also makes it quicker to go from clean, crunch rhythm, to lead with only 1 click. If you’re on clean, you turn the pedal on to get crunch….but if you want to go from clean to lead, you preset the boost before you turn on the pedal. So it’s 1 click when you're ready to go to a solo. If the boost worked separately like 2 pedals, then you’d have to hit 2 buttons to go from clean to boosted lead.
