Rare Vintage VOX Series Ninety Solid State Preamp – Universal Mod, One-of-a-Kind

Extremely rare VOX Series Ninety Solid State Preamp (1970s). Normally, these preamps were designed to work only when connected to a matching VOX amplifier. This unit, however, has been carefully modified to function as a standalone preamp that can be used with virtually any amplifier – tube or solid state. What makes this listing unique is not only the rarity of the Series Ninety line (produced in very limited numbers between 1969–1971), but also the fact that: • On Reverb, complete Series Ninety sets (head + cabinet) have sold for around $1,100. • Single preamps almost never appear on eBay or Marketplace, and when they do, they are usually non-functional or tied to their original power system. • This preamp has been professionally adapted with a custom front-panel output and external 31.5V power supply, making it plug-and-play with any amp. Features: • Authentic vintage VOX reverb & tremolo • Classic Top Boost EQ & booster • Added front output jack for direct amp connection • Powered via external 31.5V supply (included) • Works as a true preamp for both studio and live rigs Condition: Fully functional, tested, with true vintage VOX character. Modified for universal use. Sold as-is Why this is unique: Unlike the few existing listings, this unit is ready for use today with any amplifier. It combines the rarity of a 1970s VOX collectible with the practicality of a modern preamp. Perfect for collectors, studios, and guitarists who want a one-of-a-kind piece of VOX history.
