The Sonic Fields Fat Cat Overdrive is a classic JRC4558 opamp based overdrive pedal. It has a 3-band EQ instead of a standard tone control and there's a blend control to blend in some clean signal, which makes it suitable for both electric and bass guitar or even acoustic guitar.

This overdrive can be transparent and almost clean or full driven with an EQ shaped to taste and everything in between.

- Controls: Drive, Blend, Level, Body (Low), Punch (Mid) and Attack (High)
- JRC4558 opamp
- Lumberg jacks
- Alpha pots
