The Avenger is not just a guitar amp it’s a history lesson. It can give the sound made famous on classic Rock, Soul, and R&B records of the Sixties and Seventies. It is based on the “Blackface” Princeton and Deluxe Reverbs with that warm reverb and shimmering tremolo. It is available in a 20 or 25 watt combo with 6V6 output tubes.
