Description

The Grace Design ROXi Microphone Preamplifier is a compact yet formidable tool designed for musicians who refuse to compromise on sound quality, whether in a studio or on stage. This pedal brings the renowned sonic clarity of Grace Design into a rugged chassis that fits seamlessly onto any pedalboard. With its versatile connectivity options, the ROXi is ready for any gig or recording session, accommodating both microphones and instruments.

At the heart of the ROXi is its 3-band EQ with sweepable mids, which offers precise tone-shaping from subtle enhancements to dramatic changes. This makes it perfect for vocalists and instrumentalists alike, who can craft their sound with ease. The onboard footswitches offer immediate control over boost, mute, and the FX loop, allowing for a dynamic performance without missing a beat. The ultra-quiet signal path ensures your sound remains pristine, even when cranking the gain up to its impressive +55dB range.

Designed for the modern musician, the ROXi includes a highpass filter to tackle unwanted noise and a phase polarity switch to maintain sound integrity. Its power capabilities are equally impressive, with a universal power supply that travels anywhere you need to go, and a 9V power output to feed other pedals. Whether you're a solo artist or part of a band, the ROXi is your all-in-one solution for high-quality sound on the go.

Review: Grace Design ROXi & REX

recordingmag.com

Grace Design's ROXi preamp is a powerhouse with its studio-grade clarity and versatility, offering impressive headroom and an array of features like EQ and FX loop. However, the need for constant FX loop engagement for a full wet mix might irk some users. Its sibling, REX, sheds some features for a more compact form but retains the essential quality and tone-shaping capabilities. Both units are robustly built, ideal for both live and studio settings, though the premium price tag reflects their high-end pedigree. Ultimately, these preamps are a stellar choice for those ready to invest in consistent, high-quality sound.

Grace Design Rex & Roxi

soundonsound.com

Grace Design's ROXi Microphone Preamplifier impresses with its robust build and studio-quality sound, cleverly bridging the gap between professional audio and playful versatility. Featuring a unique stompbox-friendly effects loop, it caters to both studio engineers and live performers. The ROXi shines with a pristine preamp and flexible EQ, while the smaller Rex offers core features at a more accessible price. However, the XLR-only input on the Rex might limit some users. Overall, these preamps deliver exceptional quality and innovative design, making them a worthy investment for those seeking superior control on stage or in the studio.
