Audio engineer/designer Michael Grace originally began building single-order custom audio products for a small, devout following of recording engineers and artists in 1990. Before long, the word had spread about Michael's custom microphone preamp designs, which were said to outperform anything else that was commercially available. Based on an increasing demand for this mic preamp, in 1994, Grace Design was founded and began production of the original model 801 microphone preamplifier. Over the years, Grace Design has maintained a steady, methodical pace to developing new products and technologies. Their product line has evolved into a definitive collection of microphone preamp configurations and other unique professional audio products, available through Vintage King Audio.
