ST-60A: 60-watt all-tube amplifier with tri-mode rectifier
ST60A

The ST-60A has a 100% all-tube signal path that combines Sovtek 6L6 power tubes with 12AX7 preamp tubes for solid tube tone and classic breakup. Capable of monstrous gain, extreme distortion, and sparkling clean tones through 2 channels. The Clean and Overdrive channels have their own sets of volume and EQ controls (3-band bass, mid, and treble), with 2 Gain knobs and an interactive Contour control (Gain 2) on the Overdrive channel.

You can further shape your tone by selecting 3 rectifier settings. The solid-state setting delivers the tightest low-end definition and fastest attack. Tube A gives you a vintage attack and feel with the warmest sound. Tube AB1 is in-between the first two: punchy, warm sound with more definition than Tube A. Roadworthy 13-ply Baltic birch construction protects that circuit path from damage so you get reliable performance.
