T40/20 Head

40/20W 2-Channel Amp w/ Spring Reverb

The Hiwatt T40/20 Head is great for the Studio or performing on Stage. British Engineered to provide 40W (or 20W) of Classic Hiwatt Clean with an additional 'tube screaming' Overdrive Channel, this 'Cathode Biased' (Class A) Amplifier provides the Guitarist with a ‘touch sensitive’ feel to the amps response. Like the Original Hiwatt Custom Shop ‘Studio/Stage’ - this amp allows you to half your power, drive the Tubes harder, and obtain pure, natural Hiwatt Overdrive with less volume. Also features an FX loop and spring reverb.
