This versatile amp head is equipped with two channels—Classic Gain and Ultra Gain—allowing you to seamlessly switch from pristine cleans to a heavy, saturated crunch.

Its built-in digital reverb adds a lush ambiance, while the dedicated Resonance control gives you the power to tweak the low-end response to your liking. With the included 2-way footswitch, you can easily toggle between channels and engage the effects loop for seamless transitions during live performances.
