Supro 1822RTB Delta King 12 Combo

The tweed Supro Delta King 12 brings 15 watts and reverb together

The Supro 1822RTB Delta King 12 Combo is a 15-watt tube amplifier with a 12-inch Supro DK12 speaker and built-in reverb. This tweed version combines a striking finish with an intuitive control panel. For guitarists looking for their first tube combo, it offers a practical way to learn how volume, tone control, and reverb together shape the sound of a guitar amplifier.

The preamp uses a 12AX7 tube and the power amp a 6L6. With Treble, Mid, and Bass, you can adjust different parts of the tone to suit your guitar and playing style. The built-in reverb adds echo when you want to give chords more space, but can also remain subtle for a more direct sound. This allows you to experiment with different settings while practicing and hear what works for your playing.

The controls consist of Volume, Treble, Mid, Bass, Reverb, and Master. The additional Mid control provides more command over the midrange, while the Master offers a separate setting for the overall level alongside the Volume. The amplifier has a Line Out connection and no effects loop. The 12-inch Supro DK12 speaker and the 15-watt output bring a complete amplifier setup together in one combo, without the need for a separate cabinet or external reverb.

The cabinet is made of poplar and finished with tweed tolex. The dimensions are 43 x 19 x 41 cm and the weight is 13 kg. This makes the Supro suitable as a permanent amplifier for home or the rehearsal space, with all basic controls clearly arranged on the front panel. The combination of a 12-inch speaker, tube amplification, and built-in reverb makes the Delta King 12 an accessible step toward a more expansive amplifier sound.
