Supro 1808 Blues King 8 1-Watt 1×8″ Tube Combo Guitar Amp

The Supro 1808 Blues King 8 is a modern rendition of the low-wattage Supro amplifiers that were produced in Chicago during the mid 1950s.

Every element of the Blues King 8 amplifier was developed from scratch to deliver the legendary headroom and dynamics that define the vintage Supro sound. This timeless tonal recipe includes a genuine Class-A all-tube signal path, custom 8″ speaker and vintage-style wood cabinetry.

When your guitar signal hits the front end of the Blues King 8, it goes directly into a 12AX7 tube preamp, where the audio is gained up and sent to a 12AU7 triode power amp that is capable of delivering a whopping 1 watt of pure American guitar tone. The Blues King 8 stays true to the Supro legacy by faithfully delivering a broad palette of clean and dirty tones for professional recording and home practice environments. Simply put, this little amp produces an enormous studio sound when placed in front of a microphone.

The front panel of the Blues King 8 offers Volume, Tone and Master Volume controls, along with a footswitchable Boost function that adjusts the gain of the tube preamp. The Blues King 8 also features a Line Output that allows this combo amp to double as an outboard tube distortion unit feeding another amplifier or DAW. The Line Output in the Blues King 8 is conveniently located before the Master Volume, allowing you to crank the preamp gain while blending in the sound of the on-board 8″ speaker to taste.

The vintage-inspired poplar cabinetry is based on the mid-50’s Spectator model and comes loaded with a BK8 speaker. This custom-made, 8″ driver was specifically designed to capture the magic of the original field-coil speakers used by amp makers at the dawn of the electric age.

Classic power section for superior tone
The secret to the classic Supro tone is the power amp. True to the originals, the Blues King 8 has a vintage style power section and Class A tubes. This construction allows the amp to pump out crunchy tones that sit perfectly between rock, blues, and country. The Blues King 8 has simple controls to let you shape the sound. You can tweak the input volume, master tone, 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 waking the dead.

Custom-designed speaker
Another thing that sets the Blues King 8 apart is its custom-made 8″ speaker. This speaker is designed to capture the essence of the original speakers that made Supro famous. This speaker has a bold midrange that breaks up perfectly as you increase the volume. And guitarists enjoy the line output that eliminates the need to mic your amp for recording.
