If you're looking to recreate Jimmy Page's famous sounds from Led Zeppelin I and Led Zeppelin II, the Supro Dual-Tone reissue was designed just for you. When turned past noon, the volume pushes out an articulated, clear grind to give you those iconic saturated rock tones. Living up to its name, the Dual-Tone boasts two channels with independent volume and tone controls but that share a link. Plug in to the IN 1+2 input and you tap into both preamps, doubling both your input signal and your gain. Supro's Dual-Tone reissue is perfect for those looking for a great amp that facilitates the building of incredible rock grit.
