Hiwatt T40/20 Combo 1x12

Forty watts of EL84 power into one 12-inch Octapulse 100-12, wired at 8 ohms. The T40/20 1x12 combo is the Tube Series amp that covers most gigs on its own.

Power scaling takes it to 20 watts when the headroom is not wanted, and the 2024 redesign brought a wider EQ and a revoiced gain channel with more overdrive on tap. Two ECC83s and an ECC82 run the preamp; behind them sit a true spring reverb tank and an effects loop, both footswitchable, plus a line output.
