Overdrive OD-9

The OD9 represents Maxon's evolution of the OD808 circuit. While maintaining the essential JRC4558D-based Tube Screamer character, the OD9 adds refinements for modern applications.

Same Drive, Tone, and Level controls as the OD808. The core circuit retains that mid-hump and soft clipping character. Subtle refinements address decades of player feedback since the original.

Maxon continued developing the Tube Screamer formula even as their original design became the most cloned circuit in overdrive history. The OD9 represents that ongoing refinement.

True bypass switching. Standard 9V power. For players wanting evolved Tube Screamer tone from the company that invented it.
