For sale is a Mesa/Boogie V-Twin Preamp, the original full-size, all-tube floor preamp made in Petaluma, California. This is the substantial V-Twin pedal/preamp—not a small distortion pedal—and delivers classic Mesa/Boogie clean, blues, and high-gain lead tones in a rugged footswitchable format.

The V-Twin uses two 12AX7 preamp tubes and a four-stage all-tube preamp circuit. It offers two footswitchable channels/modes at a time, with a choice of Clean-to-Solo or Blues-to-Solo operation, plus a separate true bypass footswitch. The front-panel Alternate Channel switch selects whether the alternate channel is Clean or Blues.

Controls include:

• Gain
• Bass
• Middle
• Treble
• Presence
• Master
• Clean / Blues / Solo mode selection
• Bypass and Channel footswitches

Connections include:

• Instrument input
• To Guitar Amp output for running into the front end of an amp
• To Power Amp output, voiced at a hotter level for an effects return or standalone power amp
• Mixer / Headphones output with dedicated direct-recording circuitry and a side-mounted Mixer/Headphones selector
• External Channel Select jack
• External Bypass jack

This makes an exceptionally flexible pedal for a traditional amp rig, direct recording, headphone practice, a rack/power-amp setup, or as a serious backup rig. The dedicated direct output is designed for recording-console or headphone use without having to mic a speaker cabinet.

Power requirement: 12VAC, 1A, 50/60 Hz, AC-only power supply.
[Add: “Original Mesa/Boogie power supply is included” or “Power supply is not included.”]

Mesa produced the original V-Twin Pedal from approximately December 1993 through January 2005. It is a discontinued, USA-built Mesa unit with the distinctive black chassis, tube cage, and diamond-plate enclosure.
