Used Mesa Boogie VT-Twin in very good condition. The VT-Twin has a similar layout to that of the Mesa Boogie Dual and Triple Rec amplifiers. This preamp has two channels:Clean and solo(High Gain) Channel. The clean channel has a switchable "blues" mode, which pushes the clean channel into breakup. This used VT-Twin has very minimal cosmetic wear and is fully functional. Original box not included, but the original power supply is!
