GRACE Design is a pro-audio company founded in 1994 in Boulder, Colorado—a mecca for pure audio—by Michael Grace. Grace had previously designed numerous Hi-Fi amplifiers under the guidance of Jeff Rowland, a renowned figure in the high-end audio industry. The company’s ultimate circuit designs and supreme sound quality quickly garnered global attention, establishing their products as essential staples for professionals. They possess overwhelming capability, capturing subtle acoustic nuances previously beyond reach—delivering sound that is both delicate and powerful, and realistically reproducing everything from the performer's breath to the ambient atmosphere. They offer high-end audio devices characterized by flawless circuit design and technical excellence. The GRACE Design "BiX" is a compact, single-channel instrument preamp/EQ/DI that inherits the lineage of the flagship "FELiX" and "ALiX" models, distilling that same high-quality sound into a streamlined package. It runs on 9V DC power, making it pedalboard-friendly. The BiX features a pro-audio-grade EQ designed to prioritize the source signal, allowing for precise tonal adjustments while preserving the instrument's original character. DIP switches allow users to select frequencies for the high and low bands (High: 2kHz or 4kHz; Low: 100Hz or 200Hz), enabling settings tailored to the specific instrument. The unit is equipped with two "Boost" footswitches (providing up to 10dB of boost) and a "Mute" footswitch. Its ability to fully reproduce the instrument's resonance and playing dynamics, combined with its clear, low-noise sound quality, rivals that of the higher-end FELiX and ALiX models. By realistically and vividly conveying the instrument's inherent dynamics and tone, it enables the amplification of acoustic instruments on a whole new level.
