Hiwatt TB40/20 2x12 2-Channel Combo, Spring Reverb

The crown jewel of Hiwatt’s UK-designed T-Series, the Hiwatt TB40/20 2x12 2-Channel Combo, Spring Reverb (TB4020-212C-U) delivers signature British clean headroom and dynamic valve saturation in a versatile 2x12" all-tube combo.

Driven by a quartet of EL84 output tubes paired with two ECC83 (12AX7) and one ECC82 (12AU7) preamp tubes in a touch-sensitive Class A cathode-biased circuit, this redesigned model features a wider-sweeping EQ and a revoiced Overdrive channel for expanded tonal range.

Switch seamlessly between 40W full-power mode for commanding stage headroom and crisp clean articulation, or drop to 20W half-power mode to push the EL84 power valves harder for natural tube breakup and harmonic compression at studio- and club-friendly volumes.

Shape your sound across the Normal and Overdrive channels using independent gain controls alongside a shared 3-band EQ (Treble, Middle, Bass) equipped with a pull-pot Tone Shift on the Middle control for tailored midrange voicing.

Engineered as an uncompromising pedal platform and stage workhorse, the TB40/20 includes an onboard FX loop (Send/Return) and lush real spring reverb, with hands-free channel switching and reverb toggling available via an optional footswitch (Hiwatt FS201).

Built from road-tough birch ply and loaded with a matched pair of 12" Hiwatt Octapulse 100 speakers, this 2x12" combo projects wide, authoritative British tone across any stage or recording room.
