The Colosseum is the outcome of a series of polls conducted within the Cornerstone community.
It's a dual overdrive pedal based on Cornerstone’s interpretation of the legendary Bluesbreaker and Klon circuits.
The Bluesbreaker side takes things to another level!
Cornerstone has fine-tuned the design to address the common issues that plague this classic circuit, such as low volume and dark tone.
Cornerstone also incorporated their signature Clean control, which adds clean signal on top of the overdriven signal for added versatility.
Increasing the Clean control also restores some bottom end, while enhancing touch sensitivity and pick attack response.
The Klon side remains faithful to the original, with one important modification: the Clip blender.
The Klon has earned a stellar reputation thanks to the use of two mythical 1N34A Germanium diodes.
The Colosseum utilizes the same diodes but also introduces a pair of hand-selected silicon diodes into the blend.
This feature introduces an entirely new Klon flavor to your setup, while still capturing the sound of the original. It's pure magic!
 
Looper lovers, unite!
At the rear, you'll find four jacks to connect each side of the pedal with your favorite looper.
You can use the sides independently or place other pedals in between them.
