Fantastic electric guitar amplifier with built in effects. Extremely versatile and user friendly controls. I used this amplifier for recording and live performances and loved the tone and versatility, but after I built a pedal board and bought a clean tube amp, I was no longer in need of the effects. It's the perfect amplifier for beginner/intermediate guitar players that are experimenting with different genres and sounds. It features two 12" Vox special design speakers that are powered by a 100 watt, 12AX7 tube/solid state hybrid Valvetronix amplifier circuit. The control panel has eleven amp models, eleven pedal effects and two channel digital programmer. There is more information and a printable users manual at this website posted below. http://www.voxshowroom.com/uk/amp/ad100xl.html Please call, text or email! Looking forward to spread the love! Rock on!
