Versatile British Tube Amplifier for Stage and Studio!

Hiwatt stands for professional British tube tones that accompany musicians from the studio to the largest stages. The Tube series — conceived as an homage to the North American market — offers dual-channel amplifiers that deliver both Hiwatt's classic clean sound and a versatile overdrive channel. At the heart of this series is the T20/10, a two-channel amp that delivers 20 watts through EL84 tubes.

The T20/10 combines the famous clear Hiwatt tone with a powerful overdrive and also provides an effects loop plus a true spring reverb for an authentic sonic character. Thanks to the built-in power scaling, the output can be reduced to 10 watts. That lets you achieve characteristic tube breakup at lower volumes, which is particularly useful for rehearsal rooms and studios.

On stage the T20/10 proves extremely effective while offering an excellent platform for pedals. That makes it ideal for live gigs as well as creative studio work, appealing to players who value flexibility and authentic tube tone.
