The Story
Grace Design REX Microphone Preamp Pedal with Boost
The innovative Grace Design REX Microphone Preamp pedal equips artists with instant tone-shaping tools for enhancing the definition, volume, and EQ of any mic! The REX facilitates all the transparent clarity and openness of traditional Grace Design preamps, but it’s optimized for quick single-user operation. With the REX’s user-friendly features, you can shape vocals, add a dynamic boost, amplify acoustic instruments, and even monitor levels. Whether you’re an avid preamp user or a curious outsider, pros at Music Bliss can personally speak to Grace Design’s unparalleled craftsmanship and distinct preamp quality. The REX echoes the company’s legacy at a size that fits into guitar cases, backpacks, or pedalboards. Simply put, the REX is small, pristine, and — with a rugged metal chassis — ready for the road! The controls are intuitive and versatile, yet a breeze to navigate with a footswitch-activated mute. You get up to +57dB of gain on tap, a highpass filter, a 2-band EQ, an adjustable boost up to +10dB, and professional I/O spanning XLR and 1/4-inch options. Advanced users can explore the REX’s high-fidelity potential even further using an onboard FX loop for adding EQ, reverb, and more. Established acts looking for more mic control onstage and aspiring singer/songwriters needing a stage-controlled sound solution will find the REX more than delivers.
