Listing Detail Tabs

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 front end for a slightly less aggressive attack, knocking the edge down, and boosting the low end in the output EQ.

The EQ switch converts the tone from the TightDrive EQ to a new PlexEQ which gives the pedal the classic vintage stack tones....a little less mids, and the classic 412 bottom, but this FatRock version doesn't add as much sizzle as the TightRock PlexEQ does. The Gain Boost switch modifies the gain from a classic distortion sound to a very modern amount of gain. With the Gain Boost and EQ turned off the pedal can be used as a fat overdrive for an already distorted amp or pedal, without changing the character very much.
