Versatile 15-watt Tube Amp

In a nutshell, 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.

Supro Delta King 12 Combo Features:

  • Master volume control allows you to distort tones at low volume
  • 6L6-loaded, Class A power section delivers classic Supro tones
  • Custom DK12 speaker produces extra punch
  • FET-driven boost strengthens your midrange response
  • Pigtronix FAT high-gain mode unleashes huge, saturated tones
  • Custom-made analog spring reverb injects depth and dimension into your playing
  • Line output eliminates the need to mic your amp for recording
  • Optional footswitch engages boost (sold separately)

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!

Rated 5/5

Unbelievably AMAZING!!

40 years of gigging, studio recording and gear buying and I have to say this little beast has impressed me royally!!
My main amp is a Morgan PR12 but combining it with the Supro Delta King in stereo is unbelievably amazing!!
It records very nicely and can be loud if you want it to be..
This amp will for sure be in my arsenal for many years to come..
Quick shout out to my sales rep. Andy Miller, thanks for all your help, I truly appreciate your help with all my musical needs!
Music background: 40+ years gigging musician, recording artist, gear buyer.
Rated 5/5

So so close!

I'm giving this 5 stars because it's really a great little amp! First the cons:

The drive switch adds a crazy amount of volume, even more than the boost. This does vary depending on how the amp is set, it's more pronounced when playing at low volumes with the input gain really low and less so with the input gain maxed(but still very noticeable).
The boost isn't quite the volume boost I'd like but it's usable.
The preamp out and power amp in cannot be used as an FX loop, it mutes the preamp

The pros:
So light and compact. I thought it would be a about the same as the blues jr that I have but it's like 20% thinner and 3 lbs lighter.
It's loud. I haven't had a chance to practice with it but I'm sure it could keep up with a band, especially with the drive engaged.
What a classy look, mine is solid black and looks great in the living room.
Reverb is superb for the size
All of the knobs are usable across the whole range, the blues Jr gets very loud quickly and the maxes out.

The footswitch I had to buy separately works great. Utilizing the guitar volume I could practice with my band with just this amp and the footswitch.

Delta King 12

I absolutely Love my new DK12. I tend to play with out pedals and this Amplifier with my CS-336 together, well they are just made for each other!!!
Music background: 57 years trying to figure out those 6 strings
Rated 4/5

Supro Delta King love it

Nice amp blues rock it's got great cleans and can get dirty in the same jam. Built in boost and drive nice feature. I'd give it 5 stars but they don't include a foot switch which in my mind should come with every amp
You can lose with this amp 15 watt is plenty loud I will
Play out with this amp and drop a mic in front.
Man she looks sharp very classy vintage look love
That tweed.

Great Amp. !

This amp. is just fantastic. I'm very pleased with it I have been a bules and country player for many years and you can crank out the tunes on this little baby no problem and its very well built and looks great. It would have been better if they included a cover with the price the Co. got cheap with that! But overall I just love it glad I added this to my collection also I like the standby switch Fender don't have one on the Bules j. ALL & ALL PICK ONE UP YOU WONT BE SORRY, LOVE IT !
