Versatile 15-watt Tube Amp

All wrapped up in a Seafoam Green finish that's only available at Sweetwater, the Delta King 12 is a modern take on a British Invasion-era Supro from the 1960s. This 15-watt tube combo amplifier is perfect for the bedroom guitarist since it produces all the crunch and attitude of early Supro amps without the unwanted volume. The Delta King has a 6L6-loaded, Class A power section, a custom 12-inch Supro speaker, and simplified controls to provide you with perfect tones right out of the box. You'll be able to thicken up your tone with a FET-driven boost and a Pigtronix FAT high-gain mode, while a custom-made analog spring reverb injects depth and dimension into your playing. Want an amp that's descended from the classics? Choose the Supro Delta King 12.

Classic power section for superior tone

The secret to the classic Supro tone is the power amp. True to the originals, the Delta King 12 has a vintage-style, 6L6-equipped, Class A power section. This design allows the amp to pump out crunchy tones that sit perfectly between rock, blues, and country. The Delta King 12 has simple controls to let you shape the sound. You can tweak the input volume, 3-band EQ, and master volume to create your perfect sound. When you crank the input volume and keep the master volume low, you'll produce a hard-hitting saturated tone without rattling the walls.

Player-friendly features

Guaranteed to inspire, the Supro Delta King 12 has a lot of features for a pint-sized combo. Its FET-driven boost function gooses your midrange to add girth to your tone. Its Pigtronix FAT high-gain mode gives you huge, saturated tones that are certain to satiate. And its custom-made analog spring reverb offers incredible depth and dimension.

Custom-designed speaker

Another thing that sets the Delta King 12 apart is its custom 12-inch speaker. Designed to capture the essence of the original speakers that made Supro famous, this custom speaker has a bold midrange that breaks up perfectly as you increase the volume. And guitarists here at Sweetwater enjoy the line output that eliminates the need to mic your amp for recording.

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Better than I ever hoped.

Having owned quite a few 1950s and '60s Supro and Valco amps, I was hesitant to purchase a new Supro amp. Have no fear: This is an amazing sounding amp that really does sound like a Supro. Not sure how they do that. Plus, I really like walking into the music room now and the first thing that catches my eye is this seafoam green beauty. [parked next to the '59 Supro Dual Tone : ]
I highly recommend this Delta King 12. Pretty sure my sales guy said they only made about 30. Get now or kick yourself later.
Music background: Supro amp player since 1980
