Amp is in very good condition, the only problem is the potentiometer on the back for the Line Level Out control which works but feels loose.

Core Features

• Hot Swap Tubes (No Biasing Needed): You can switch the single output tube at will among almost any octal-based power tube—including 6L6, EL34, 6550, KT90, KT88, KT77, 6V6, and KT66. The two preamp tubes can also be swapped with any combination of 12AX7, 12AT7, 12AU7, 12AY7, or 12AZ7.
• Built-in Hot Plate Power Attenuator: Allows you to drive the amp into full output distortion while keeping the volume at bedroom or studio-friendly levels. It features a hard-bypass switch on the front panel.
• Built-in Dummy Load: The speaker outputs accommodate loads from 2 to 16 ohms. If you unplug the speaker cabinet entirely, the amp switches to an internal dummy load to prevent transformer damage, making it perfect for silent direct recording.
• Lightbulb Noise Reduction: A unique circuit utilizes an actual lightbulb on the front panel that glows as you play, serving as a highly effective, organic noise reduction gate. 
• Transformer-Isolated Line Out: Features an adjustable level control and a toggle switch to output either Line-Level or Instrument-Level signals
