A Whole New Vintage.

The Shelford Channel is built around Rupert Neve’s first new transformer-gain, class-A microphone preamplifier in over 40 years, a “best-of-the-classics” inductor EQ section, a tone-packed diode bridge compressor, the power of variable Silk saturation, a new dual-tap transformer output stage, and twice the operating voltage of vintage designs.
