Description

Discover the Grace Design MOXi Acoustic Instrument Preamp, the perfect studio-grade companion for acoustic musicians demanding top-notch sound on stage. Nestled snugly between Grace Design's FELiX and BiX models, the MOXi delivers exceptional audio performance through its dual-channel design. Whether you’re toggling between instruments or blending a hybrid piezo/microphone setup, the MOXi's versatile configuration is engineered to meet your dynamic needs.

Each channel is equipped with an independent 3-band EQ and a fixed 75Hz high-pass filter, offering the ultimate in tone-sculpting flexibility. For those moments when your sound needs an extra push, a footswitch activates a variable 10dB boost, ensuring your solos soar through the mix. The MOXi also features a robust FX loop with dedicated send and return jacks, allowing seamless integration of your favorite effects pedals while maintaining a pristine signal path.

Designed with the performing musician in mind, the MOXi offers flexible routing options—blend channels with the MIX mode or switch between them with the A-B mode. The thoughtful design extends to its outputs, featuring a transformer-isolated XLR DI for noise-free connectivity to audio interfaces or mixers, alongside a 1/4" line out for stage amps.

Built for reliability, this preamp is housed in a rugged enclosure, and crafted in the USA, ensuring it withstands the rigors of both stage and studio environments.
