Looking to bring that massive, warm, Ampeg-inspired tube tone to your pedalboard without the weight of a refrigerator? This Olympic MkIII is in pristine condition and ready to anchor your signal chain.​The Olympic MkIII is more than just a preamp; it’s a professional-grade solution for bassists who need consistent, high-fidelity tone whether they are going direct-to-PA or into a power amp. It features a real 12AX7 tube running at high voltage to provide genuine harmonic warmth and compression.​Features include a true tube path for authentic saturation and feel, plus built-in impulse responses based on classic bass cabinets like the Ampeg 8x10 (you can add your own cabsim via microSD). It offers flexible connectivity with a balanced XLR output for front-of-house, a dedicated headphone jack for silent practice, and an effects loop to place your pedals after the preamp stage. The classic EQ section provides intuitive control over gain, bass, middle, treble, and master volume.​Regarding condition, the unit is cosmetically and functionally perfect. There are no scratches, dents, or Velcro residue, and the tube has plenty of life left. The original box and manual are included.​This MkIII version is highly sought after for its compact footprint and the ability to load your own custom cabinet simulations via the microSD slot, making it a versatile tool for both vintage purists and modern players.
