This Grace M501 has been fully tested by our expert team and comes with a money back guarantee and lifetime support.  We have multiple units from the same studio/production run if you want matched pairs.

The Grace Design m501 is a single-channel, transformer-less mic preamp for the 500 Series format, bringing the renowned transparency of Grace Design's acclaimed m101 to a compact, modular package. Built for engineers who prioritize capturing the source faithfully, it delivers exceptionally low noise and distortion with a wide gain range of 10–75 dB. Features include 48V phantom power, a 75 Hz high-pass filter, a ¼" Hi-Z instrument input, and Grace Design's exclusive Ribbon Mic Mode — which raises input impedance, bypasses decoupling capacitors, and locks out phantom power to safely accommodate passive ribbon microphones. Hand-built in the USA and backed by a 20-year warranty, the m501 is the go-to choice for clean, detailed, and uncolored recording in any 500 Series setup.
