Besides the two aforementioned switches, the Fat Rat gives you a Distortion knob, a filter knob, an overall volume control, and a bypass/engage footswitch. A 1/4" instrument input and output are offered for your guitar, and the pedal is powered by a separately-available 9V battery through an easy-to-open battery compartment. It can also run off a 9V power adapter or an 18V power adapter, both of which are available separately.
Clipping Section
The switchable mosfet clipping section gives you subtle scoop and smoothing in the upper midrange throughout the entire gain range of the pedal, and makes the pedal sound more amp-like and natural.
Socketed Opamp
The pedal comes with a stock chip, the OP07DP. However, changing over to other opamps like the LM308 is a quick and simple mod that you can do solder-free.
Large CTS Pots
These pots give you a smooth, even sweep throughout the range of the Distortion, Filter, and Volume controls, allowing you easy access to multitudinous sweet spots within this tone machine.
Fat Switch
The Fat switch offers significant bass boost and simultaneous high cut, making the pedal suitable for bass guitar and lower tunings.
9 or 18V Operation
With a 18V power supply, you can achieve increased headroom and fidelity, as well as less sagging when compared to older RATs.
