Excellent Condition – Built with Premium Components

For sale is a CAPI VP28 (8 Units) two-stage 500-series microphone preamp in excellent working condition.

This is an earlier VP28 featuring the sought-after original Marconi-style knobs that many CAPI enthusiasts prefer. In addition to the vintage-inspired aesthetics, this version delivers the classic VP28 sound that helped establish CAPI's reputation among engineers looking for API-inspired tone with expanded flexibility and significantly more color options.

The VP28 is a true two-stage design featuring three transformers and two discrete op amps, allowing everything from clean, punchy preamp tones to rich transformer saturation and harmonic coloration. With stepped gain and output controls, it's easy to dial in repeatable settings while exploring a wide range of textures.
