Description

Fat BAT is our take on Ibanez FC10 Fat Cat circuit with the ability to enter Ibanez LA Metal and Fat Rat territory. We've used NOS (new old stock) NE5534 and NOS 741 operational amplifiers. You can explore different voicing selecting between 6 clipping options: red LEDs (like Turbo Rat), LA (op-amp clipping - very loud), NOS Soviet D9 Germanium diodes (similar to Your Dirty Rat), Si 1N914 diodes (same as classic Fat Cat), soft (op-amp feedback loop), Si BAT85, Fat Rat style BS170 MOSFET and Si 1N914.

About the name

The "Fat Bat" expands our Bat series of pedals, which are inspired by the legendary RAT distortion and its many variations. This pedal's name is a direct nod to its core circuit, which is based on the Ibanez FC10 Fat Cat, a classic and robust distortion pedal. Staying true to its name, the "Fat Bat" also features a special mode that sonically mirrors the sought-after ProCo Fat Rat, offering a fuller, warmer, and more powerful take on the aggressive character that defines the Bat-family.
