From the vendor
Project overview
The Dirty Freeman overdrive pedal crams all the British-style grit, supple touch sensitivity, and tonal flexibility of its namesake all-tube amplifier head into a pedalboard-friendly enclosure. It includes a tight switch to reign in your amp’s low end when being pushed.
Introduction
• This board has been designed for on-board pots and switches and keeps your project tidy without long cables around.
• Works using four TL072.
• Internal Trimpot to set the max amount of gain at taste.
• Fits on a 125B enclosure with top-mounted jacks.
If you like this pedal, we recommend taking a look at our Freeman Unchained. This new launch is inspired by the BE-OD Deluxe, a dual pedal that features the BE-OD and Friedman’s Dirty Shirley together, unleashing the full potential of the Friedman brand in a single board.
