Mesa/Boogie Strategy 400 Stereo Tube Power Amp – Rare Version 3 (Front Presence)

1 item left

The Ultimate "Twelve-Pack" of Tone

Own a piece of heavy metal history. The Mesa/Boogie Strategy 400 is the undisputed king of all-tube power amplifiers, famously used by James Hetfield and Kirk Hammett to define the "Black Album" sound. This specific unit (Serial #S1833) is the highly coveted Version 3, featuring the factory front-panel Presence controls for precise high-end tailoring without reaching behind the rack.

KEY FEATURES & CONDITION:

  • Condition: Excellent condition
  • Pure Power: Delivers a massive 200 Watts RMS per channel (400 Watts total) via a legendary 12-tube power section.
  • Version 3 Specs: Unlike earlier versions with toggle switches or no presence controls, this unit offers fully sweepable Presence knobs on the front panel.
  • Built Like a Tank: Hand-built in Petaluma, CA. This unit provides the immense headroom and "explosive" low-end punch that modern digital or lightweight amps simply cannot replicate.
  • Legendary Headroom: Ideal for players using high-end preamps (Mesa Quad, Triaxis, or Fractal/Kemper) who want the authentic "push" of a real tube power section.

Note: Due to the massive weight of the transformers and the 16-tube complement, this unit is a true heavyweight of the rack era. Serial #S1833 is a clean, well-preserved example of Mesa engineering at its peak.
