The Delta King 12 combo captures the essence of the vintage Supro amplifier sound that was instrumental in shaping the early electric Rock & Roll and the British Invasion of the 1960s. Its Class A single-ended tube amplifier provides the same raw tonal characteristics and remarkable dynamic response as its mid-20th-century counterparts, while delivering a robust 15 watts of 6L6 tube power through a custom 12-inch DK12 speaker. Key features include front-end gain via a 12AX7 tube preamp, a FET-driven boost function, the Pigtronix FAT high-gain mode, a 3-band EQ, master volume, and a specially designed genuine analog spring reverb.
