TNC ACMP-84 Microphone Preamp Vintage-Style

No sales tax for customers outside California.  

The TNC ACMP-84 is a boutique-style microphone preamp inspired by classic Neve and Calrec channel strip designs, offering rich analog warmth and detailed harmonic response. Built in limited quantities, this preamp features transformer-balanced inputs and outputs, Class A circuitry, and an EQ section modeled after vintage British consoles. Engineers value the ACMP-84 for its bold low end, smooth midrange, and airy top, making it an ideal choice for vocals, guitars, drums, and acoustic instruments.

This unit is in excellent working condition with clean controls and no functional issues. Its sound has been widely praised for delivering high-end studio character at a fraction of the cost of original vintage units. The preamp’s EQ section is musical and responsive, allowing subtle tone shaping or more aggressive coloration when pushed.

At Mahar’s Vintage Guitars, every piece of gear is tested, photographed, and accurately represented. We welcome trades and also buy quality recording and musical equipment. Pair this preamp with one of our vintage microphones or explore our Fender Amplifiers Collection and Sell or Trade Your Gear page for more options.

The ACMP series gained a cult following in the early 2000s for offering transformer-based preamps inspired by vintage Neve and Calrec consoles. While not tied to specific famous engineers, many home studios and indie producers adopted them as an affordable path to boutique tone.
