Supro Delta King 8 Review

Supro Delta King 8 Review Demo

One watt sounds monstrous in this '50s-meets-modern mighty mite.

Solid class A tone at an affordable price. Responsive and fun to crank. Simple design. Line level signal from the line-out jack adds useful functionality.

Probably too quiet for a gig-able clean tone.


Supro Delta King 8


Since its 2014 revival, Supro has given fans of small, low-wattage combos plenty to talk about. This should come as no surprise. Tiny but ferocious amplifiers with the Supro logo have been on the scene since the early days of the electric guitar and landed on some of the most classic guitar records of all time. And the company's recent offerings have captured the sonic essence of those vintage models with a line of well-built, modern amps that look just as cool as they sound.

Thus far, the current Supro team have drawn inspiration primarily from their 1960s models. But the new Delta King series digs in a little deeper, delivering the sound and aesthetics of their 1950s combos—stripes and all. The Delta King 8 is the tiniest of the bunch, offering just 1 watt of all-tube class A power via a single 12AX7 preamp tube and a single 12AU7 power tube. While it may be small, this amp lives up to the sonic legacy of its vintage predecessors and projects a surprisingly fearsome roar.

Robust, Balanced, and Nasty

Playing the Delta King 8 is immediately satisfying. Using Telecaster- and Jazzmaster–style guitars, I set all three knobs—volume, tone, and master—to noon and got a clean, smooth, midrange-focused tone. This is, however, just about all of the clean volume that this amp has to offer. Turning the volume knob above noon gently eases the combo into an overdriven sound that, at full volume, is gnarly and cutting but retains warmth and clarity. The boost switch bumps the volume and adds a little more gain. Naturally, I had the most fun with everything cranked and the boost on. But while it's impressively loud for 1 watt, the Delta King 8 will be most useful for recording, practicing, or for extremely quiet gigs.

Turning the volume knob above noon gently eases the amp into an overdriven tone that, at full volume, is gnarly and cutting but retains warmth and clarity.

The 8" Supro DK8 speaker sounds robust and balanced, and easily handled the overdriven tones without sounding trashy. I've probably spent too much of my life wondering about speaker swaps for other small combos, but I'd be quite satisfied with this stock speaker.

A Cure for the Backline Blues

The line-out jack on the back of the Delta King 8 provides a line-level signal that is perfect for direct recording. This feature was thoughtfully positioned before the master volume control (an unusual feature on an amp this small), which means you can get warm tube preamp tone straight into your audio interface and opt to have the speaker muted when you turn the master volume down to zero.

That isn't the only trick up the Delta King 8's sleeve. To unlock its hidden superpower, go ahead and plug the same line-out straight into another amp. In this setup, the Delta King 8 essentially becomes a tube-driven overdrive unit. Chronic sufferers of the backline blues will celebrate the fact that this little Supro can lend its low-watt, class A tone to bigger, flatter-sounding stage amps. I was blown away by the snarling sounds it generated with my Deluxe Reverb at very reasonable volumes. And by keeping the master volume up on the Supro, you can also create cool A/B blends if you mic up both amps. If you're used to playing house gear but can figure out a way to schlep an extra 15 pounds, this tiny amp could be a game-changing addition to your gigging rig.

The Verdict

The Delta King 8 delivers much of the vintage Supro experience in a hip, well-built package. It's fun, sounds good in clean settings, and great in more overdriven ones. At $449, it's a great deal for those reasons alone. But the convenience and versatility that comes with the addition of the pre-master line out opens up possibilities in the studio and offers solutions to backline woes that make the price even more appealing.
