*This limited edition Blacked Out 2025 Chicago Rat is limited to 200 units

Note: THIS IS NOT A RAT CIRCUIT!! Just aptly named in homage to our home town being the Rat population leader of the USA for 10 years in a row now.

What you are looking at is a true collaboration, and experiment if you will, with fellow Chicagoan Rob Scallon. Many of you are here after watching the newly released documentary of this project from Rob’s Youtube channel. We wanted to create a circuit from scratch that was somewhere along the lines of an old school style distortion or a vintage fuzz, so we did both in one killer box!

In short, the Chicago Rat is a 2 stage op amp gain pedal with selectable modes for either high gain distortion, or nasty over clipped fuzz with a starve control knob to take it all the way to sputtering filth. Gnar Gnar to the nines, straight outta the gutter.

The distortion side (Normal) is hot rodded crunchy gain with lots of output. The starve control (Bleed) is defeated in this setting. Crank it up and blast away. The fuzz setting (Rabid) adds gain and tons of clipping along with engaging the Bleed section to allow ample adjustment of just how disgusting you want it to sound. You’ll hear the texture and gating increase as you turn it clockwise.

These are all built in Chicago by Johnny @ Daredevil HQ, housing through hole components, true bypass switching, and an external 9V DC jack for power supply.
