Solid State 25W modeling amp. 10" speaker. Has many controls and has 100 pre stored effects. It emulates all Marshall tube and solid State amp sounds, 'American' amps too. Clean, Distortion, Reverb, any effect imaginable. You can download many more (for free) and can dial in specific sounds/tone that emulate guitars on your favorite songs. It is Bluetooth capable and can be controlled via your phone with (free) Marshall CODE app. It doubles as a powerful Bluetooth speaker as well. It sounds really good and I will include the matching Marshall CODE ($80) footswitch . You can pre program 18 presets/ tones to footswitch and select and cycle through them while playing.
