Designed to easily deliver the nuances of the "Hiwatt sound" that characterized the rock scene of the 1960s and 70s (think Pete Townshend of The Who and David Gilmour of Pink Floyd). Despite its small size, you can enjoy the incredibly clear and focused sound known as "crystal clean," a hallmark of HIWATT. It takes effects pedals very well, making it suitable for players who build their sound with their pedals. The red switch on the left (DIST/CLEAN) switches to distortion mode. Rather than a heavy distortion, it provides a gritty, vintage-style rock sound that reveals a completely different side. Please, give it a try! The unit is in good condition, with no crackling or noise. Thank you.
