Supro - Delta King 12 Ivory Black

The Supro Delta King 12 takes centre stage with its ivory and black finish, making an immediate visual impact even before the first note is played. Plugged in between two effects pedals, the combo certainly doesn’t fade into the background: the 12-inch Supro DK12 speaker delivers a dense sound that takes centre stage in the mix, whilst the built-in Boost and Drive controls, at the touch of a button, toughen up the tone without ever compromising its consistency. The Line Out allows this signal to be routed directly to the mixing desk, without a microphone or any loss of detail between the amp and the recording.
Under your fingers, the six knobs — Volume, Treble, Mid, Bass, Reverb, Master — offer a firm, almost notched feel, encouraging you to fine-tune rather than make abrupt adjustments. The built-in master volume allows the 6L6 to saturate without requiring a full-hall volume, a rarity for a 15 W combo. The rubber handle cushions the 13 kg weight during transport, and the dual TRS footswitch jack accommodates the Supro SF2 (sold separately) to activate effects at your feet, without interrupting your playing flow. The black grille, stretched across the front panel, hints at the movement of the cone without ever revealing its exact texture.
In terms of sound, the 12AX7 preamp valve adds a mellow texture to the midrange, whilst the 6L6 output valve keeps the bass tight without weighing it down — a balance that avoids the lack of punch often criticised in smaller-format amps. The built-in reverb isn’t just an added effect; it creates an atmosphere behind the dry sound, like an invisible second room. The single instrument input simplifies the signal path and enhances the clarity of the upper midrange. The poplar cabinet, finished in ivory-coloured Taco Tolex with black piping, delivers a crisp and precise resonance, perfectly in keeping with its bold two-tone look.
