Three Big Sounds …with individual control and total conviction: Rhythm 1 feels bouncy and shimmers with freshness. The Lead Mode is blistering high-gain focus. And Rhythm 2 covers that elusive middle ground. This mode alone can produce an alternate Clean, a purring Blues or a grinding Crunch.
All this and the elusive magic of Simul-Class™ …our patented way of enriching a power section. Think of it as two different power amps working simul-taneously. One extracts the juice of Class A sweetness while the other delivers the high power punch of Pentode Class AB.

This is a later Mark IV B model with a Series, Mono Send / Mono or Stereo Return Effects Loop that operates manually or can be assigned to any one or two modes.

Also selling separately a CabClone IR Plus cab simulator and attenuator as seen in last pic.

Local buyers only. Will not ship.
