Juan Alderete Playing Bass Through Amptweaker’s FatRock Distortion Pedal

Juan Alderete, bassist with Zavalaz (previously with The Mars Volta) went by the Amptweaker booth at 2013 Summer NAMM and checked out the FatRock on bass. He was impressed. The tone changes we made to go from the normal TightRock to the FatRock are similar to the changes used to create the Bass TightDrive from the guitar version….so naturally this one works great for bass if you need a higher gain tone.

While the FatRock was designed for guitarists, the changes made are similar to those used to convert the TightDrive to a Bass TightDrive, specifically sliding the Tight control down in frequency and increasing the lower range of the Tone control.

Since its introduction, the TightRock has been very popular, but as usual Amptweaker received many requests for a variation…..the new FatRock is the culmination of discussions on online forums, from players who wanted a warmer version that worked better with brighter guitars and amps. All features are identical to the TightRock, but the tone has been tweaked to extend the low range of the Tight and Tone controls, add a fixed Fat boost at the frontend for a slightly less aggressive attack, knocking the edge down, and boosting the lowend in the output EQ.

The SideTrak™ effects loop is a popular Amptweaker exclusive feature. This extra effects loop turns OFF when the pedal is ON and 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 the rhythm or lead sound…all without having to hit more than one pedal….it’s like having a built-in A/B box.

Standard effects loop with Pre/Post switch is also included on the back, as well as the LED illumination of controls, Battery On/Off switch, and magnetic battery access door.
