Very Good, with GA-FC footswitch.

From Boss:

"Combining classic tube sound and feel with next-generation tonal diversity, the BOSS Nextone series presents an exciting new concept in professional guitar amplification. Distinctive channel voicings deliver a wide range of inspiring tones, while four selectable Class AB analog power amp types provide instant access to the unique characteristics of 6V6, 6L6, EL84, and EL34 output tube sections. Backed by our advanced Tube Logic approach, each power amp type re-voices the entire circuit from input to output, putting the complete sonic experience of these signature power stages in one amp for the very first time.

Want to dive deeper with even more sound customization? Just connect to the Nextone Editor and become a virtual tech, fine-tuning bias, sag, and other internal settings to perfectly match your individual style and touch. Nextone also includes convenient modern features for stage playing, such as built-in effects, a line out for mic-free direct tone, and a power control for expressive cranked-amp sound at manageable volumes. And thanks to Tube Logic, you get to enjoy all the great sound and response of your favorite tube designs without the backbreaking weight and ongoing maintenance hassles."
