This versatile unit combines a Class-A high-voltage tube preamp with a comprehensive dynamics and EQ section, allowing you to shape your sound from crystal clear to warmly distorted.

With features like soft and hard-knee compression, AutoVelocity and OverEasy modes, and PeakStop limiting, you have full reign over your signal's dynamics.

Connectivity is a breeze with 1/4-inch and XLR inputs and outputs, alongside a convenient front-panel instrument input. The vintage VU meter not only adds a touch of old-school flair but also offers clear visual feedback on your levels.
