KINGLY. The Delta King 12 combo captures the vintage Supro amp tone that helped sculpt the sound of early electric Rock & Roll and the British Invasion of the 1960s. Its single-ended Class A tube power amp provides the same raw tonal characteristics and remarkable touch sensitivity features of its mid-century counterparts, all while delivering a full 15 watts of 6L6 tube power through our custom 12-inch DK12 speaker. Features include front-end gain via a 12AX7 tube preamp, a FET-driven boost function, Pigtronix FAT high-gain mode, 3-band EQ, master volume, and custom-made genuine analog spring reverb.
