Product Details
Brand: THD

The Univalve’s claim to fame is its plug-and-play tube swapping. Because it is a single-ended Class A design, you don't need to match tubes or adjust the bias. You can literally pull out an EL34 and pop in a 6L6, KT66, or even an old 6V6 while the amp is off, wait a minute for it to warm up, and have a completely different tonal foundation.

  • Built-in Hot Plate: It includes a legendary THD Hot Plate power attenuator, allowing you to crank the power tube to full distortion but keep the volume at "don't wake the neighbors" levels.
  • The Light Bulb (Noise Reduction/Compression): There is a literal automotive light bulb on the circuit that acts as a subtle compressor and protects the transformer. When you hit a power chord, the bulb glows, absorbing excess energy.
  • Dual Inputs: * Roll: Lower gain, classic "glassy" cleans.
    • Rock: Higher gain, ranging from classic crunch to heavy saturated overdrive.
