Hiwatt TB40/20 – Portable British Power with Modern Control
The Hiwatt TB40/20 stands as the crown jewel of Hiwatt’s UK-designed T Series, reimagined for 2024 with expanded tonal control and a more expressive gain structure. Built around Hiwatt’s signature preamp design, the TB40/20 delivers authoritative British tone with enhanced flexibility—crystal-clear cleans, touch-responsive overdrive, and the unmistakable punch and clarity the brand is known for.
Driven by a blazing quartet of EL84 output tubes, the TB40/20 offers a dynamic, reactive feel that responds effortlessly to your picking attack and guitar volume. A revoiced overdrive channel broadens the range of gain on tap, while the newly widened EQ provides greater shaping control without sacrificing Hiwatt’s classic voice. Power scaling allows you to switch between full 40-watt operation for maximum headroom or a reduced 20-watt mode for earlier breakup, compression, and studio-friendly volumes. With a built-in FX loop and true spring reverb, the TB40/20 is equally at home as a refined pedal platform or a self-contained tone machine for stage and studio.
