  • $89999


Tap into mid-’60s Chicago blues guitar tone with the Supro Blues King 12 tube combo amplifier. Based around Supro’s unique Class A power section and a custom Supro BK12 speaker, the Blues King 12 delivers the classic grind and crunch that Supro amps are known for.

A foot-switchable boost adds girth to your tone, perfect for fattening up single-coil pickups. A high-gain mode gives you the drive and sustain you need for sweet lead tones. Complete with an effects loop, real spring reverb, and 3-band EQ, the Supro Blues King 12 tube combo is ready to gig.

Classic tube tone

Guitarists love the way Supro amps sound when you push them hard, and the Blues King 12 combo gives you options when it comes to dialing in your own signature sound. For a more modern sound with preamp distortion, dial up the Volume control while dialing back the Master control. For the vintage grind of a saturated power section, crank up the Master control and reduce the Volume control to clean up the preamp section. Either way, if you need more gain, simply kick on the gain boost.

Effects loop and line out

The Supro Blues King 12 combo is equipped with an effects loop and a line output for maximum flexibility when it comes to setting up your rig. Many players prefer an effects loop for things like reverb and delay, but it’s also a great way to use amp-in-a-box preamp/distortion pedals — just connect your preamp pedal of choice to the Blues King’s return jack, and you’re ready to rock.

Custom 12" speaker hits hard

Supro combo amps are well-known for their rich midrange character. A big part of that signature sound is their custom speakers, like the Supro BK12 in the Blues King 12 combo. Cranked up loud, it’s like a punch in the chest. Even at more reasonable volumes, the Blues King 12 delivers powerful lows that remain tight, an enchanting midrange character, and smooth highs. Complete with a 3-band EQ, the Blues King 12 is the perfect platform for blues, rock, country, and more.
