The Swart Stereo Master is the 20 watt + 20 watt big brother to the amazing ST-Stereo. In addition to more output, the Stereo Master adds a Master Volume to the circuit.

This unique amp has really been a long time coming but the wait is worth it. This is Swart Amplification's greatest 6V6/6L6 stereo push-pull effort to date. Dual 20 watt handwired amps in one chassis, each with separate controls for EQ & Tone along with all-tube driven spring tank reverb and dual Tube Tremolos with a unique Stereo Master Volume control. Simply put, you have to hear it to understand how BIG this thing sounds. The dark tweed head is truly something special. And it will take 6V6 or 6L6 for a bit more headroom. Rectifier options include 5AR4, 5U4, and 5Y3 for most sag/compression and sweetness.
