Supro Blues King 8 1x8" 1-watt Tube Combo Amp

You don't need a loud, roaring amp for electric blues. A small, low-wattage amp like the Supro Blues King 8 is the perfect companion to lazy afternoons where you just feel like letting loose to some backing tracks in A minor to let off some steam.

Despite its 1 watt rating, it still puts out an impressive volume for home use especially when cranked.

Cranking the Blues King 8 rewards you with sweet saturation that is otherwise unattainable with higher wattage amps without disturbing the neighborhood.

It features a 12AX7 Preamp Tube and a 12AU7 Power Amp Tube.

The boost is switchable via external footswitch. An 8" Supro BK8 rounds out the little combo.

The Supro Blues King 8 gets a lot of love from blues veterans and newbies alike. The tone is described as "soulful" and a much better alternative to solid state equivalents in terms of feel and expression. Some studio engineers also found it a great recording amp. One user inspired by Billy Gibbons' use of a miked up Pignose practice amp, successfully used his Supro Blues King 8 for live use (miked up, that is).

People knew exactly what kind of amp they were getting and Supro does a great job of setting that expectation so we found very little in terms of complaints with the amp. One person wished there was at least reverb, but they admit that would be asking too much already.

The Supro Blues King 8 is an amazing little amp that could. At low to mid gain, you're given a nice clean and edge-of-breakup tone, perfect for the hits of yesteryear. At full volume, you get a howling blues tone that could delve into early punk if you want.

Unfortunately this is no longer available new in stores but you can see excellent alternatives in our guide to The Best Tube Amps for Guitar.
