The best of both worlds just got better. Spider Valve™ MkII guitar amplifiers provide a boutique-style, all-tube design created by Reinhold Bogner, the most advanced amp modeling that Line 6 has to offer, and extremely deep but simple FX editing. Spider Valve MkII amplifiers are the result of a groundbreaking collaboration between Line 6 and Reinhold Bogner. Boutique-style amp designs combine with the most advanced Line 6 amp modeling to deliver muscular tube tone and unsurpassed sonic flexibility. The amp and effect modeling flows into the Bogner-designed 12AX7 preamp and 6L6 power amp, and the result is a guitar-playing experience unlike any other. Does lugging a lot of gear really build character? Spider Valve MkII amplifiers are the sole solution for working guitarists. Each amp features killer front-end flexibility (industry-standard amp and effect models, full editability, 128 user presets), to match Bogner's back-end brawn (all-tube design, muscular tone, boutique-style response), all under one roof.
