Used Revv D20 Rackmount Tube Amplifier Head

This Revv D20 is an all-tube, 20/4-watt lunchbox-style guitar amplifier head famous for being the industry's first amplifier with embedded Two Notes Torpedo reactive load and virtual cabinet (IR) technology. It functions as a clean-to-crunch pedal platform that can be played through a traditional speaker cabinet, used silently with headphones, or plugged directly into a recording interface or PA system without needing a speaker load attached.

Overview & Description

• Tone Character: Designed around a Californian-style clean and light-overdrive voice with high headroom, serving as an ideal pedal platform.
• 
  
• Power Scaling: Switchable from 20 watts down to 4 watts (where the power section sags for vintage-style breakup at lower volumes).
• 
  
• Two Notes Integration: Features an onboard reactive load box and virtual cabinets, letting you choose from factory cabinet presets, load custom IRs via USB/MIDI, and send a balanced XLR direct signal to a stage PA or DAW.
