The Supro Delta King 12 IB tube guitar combo amplifier offers authentic vintage sound with modern reliability and features 15 watts of Class A single-ended power through a 6L6 tube power amplifier. This white combo amplifier measures 43.0 cm in height, 41.0 cm in width, and 19.0 cm in depth, weighing 13.0 kg for stable performance. It integrates a specially designed 12-inch DK12 speaker for Supro amplifiers, delivering the raw tonal characteristics and playability that defined early electric rock and British Invasion sounds. The gain of the input stage is controlled by a 12AX7 tube preamp and offers three different gain levels: standard drive, FET-controlled boost function, and Pigtronix FAT high-gain mode for versatile tone shaping. The comprehensive control panel includes master volume, drive, volume, a three-band equalizer with treble, bass, and mid controls, reverb level, and boost activation. The genuine analog spring reverb system provides authentic vintage reverb effects, while the single-channel design maintains simplicity and focus on the core sound. Three input jacks allow for various instrument connections, and a footswitch input enables remote control of boost and reverb functions. The amplifier operates with a 240V power supply and includes a power cable but does not offer an external effects loop, headphone output, or Bluetooth connectivity. With careful attention to construction detail, this amplifier combines historical sound authenticity with reliable modern build quality, making it suitable for both studio recordings and live performances where vintage tube amplifier characteristics are desired.
