Koch Twintone Combo

The Koch Twintone Combo is a premium 50-watt all-tube amplifier that delivers rich tone, reliable performance, and outstanding build quality. Built in the Netherlands, it features a matched pair of EL34 power tubes and four 12AX7 preamp tubes, offering beautifully balanced clean tones, dynamic crunch, and soaring lead sounds across three footswitchable channels—Clean, Overdrive, and Overdrive Boost.

Its user-friendly layout includes bright/normal inputs for tonal flexibility, dedicated EQ for both channels, and a solo/rhythm level control for instant volume boosts on stage. A long-scale spring reverb, series effects loop, and balanced recording out with speaker simulation add serious studio and live flexibility. Housed in an 11-ply birch cabinet and paired with a custom Jensen VG12-90 speaker, the Twintone is as rugged as it is refined. From stage to studio, this amp covers everything with confidence.
