AT-100: 100-watt all-tube amplifier with tri-mode rectifier

The AT-100 is a 3-channel, all-tube, tri-mode rectified beast that gives you unparalleled tone and astounding
versatility. The clean channel yields sparkling vintage tone that stays clean even at high volume. The overdrive section features 2 independent high-gain channels and independent volume controls with a shared 3-band EQ. The assignable contour (mid-scoop) control gives you the ability to make each overdrive channel sound radically different. The Global section features Low-Res (Resonance), Reverb and Master Volume.
