Vintage American roots, improved with modern design and build techniques. 

Now Available!

Balance, punch, fullness, and clarity are at the forefront of this speaker.  The mids are tailored and even, enabling the articulation, openness, air, and a nice glassiness to shine through in the highs.  The tight, solid, and responsive lows round out the tone and perfectly balance the detail in the highs.  A very musical speaker optimized for the ever so popular Deluxe Reverb, but suitable anywhere you want pure American tone.

  • 12” speaker
  • 50 watts
