Felix II

This one is bigger and more kitchen sink-y. This starts with a precision rotary switch gain control, which levels up the audio performance, especially in higher gain ranges (ribbon mics welcome). A 2 position high pass filter gives excellent control of problem bass / rumble areas at 75Hz or 150Hz. A 3-band EQ with sweepable mids rounds out the tone shaping. The FX loop can be defeated by a footswitch and has an onboard blend control to run your effects at 100% and adjust wet / dry amount on the preamp. The input is a combi XLR / 1/4″ jack, so it can run as an instrument preamp like its buddy ALiX .

We could keep going, but you get the idea: REX and ROXi are wicked mashups of a mic pre, channel strip and stage preamp. Plop one on your your studio desktop and boom, you have an genuine Grace Design recording channel. Tack one to your pedalboard and you have a Swiss Army knife style stompbox with astonishing audio performance and massive flexibility. Do the Swiss actually give those little red knives to their army? Let us know.

Roxi

Like its big sibling the FELiX, ALiX is built into the same roadworthy floor unit chassis, portable enough to throw in your bag or strap to your pedalboard, but still deliver studio quality sound to the stage. With the same stunning audio performance and legendary reliability as our pro audio range, ALiX brings open, musical and nuanced sonic character to any performance situation.

The same powerful eq section as the FELiX allows simple and intuitive tone shaping. The high pass filter cuts 12dB per octave from 20Hz to 1kHz, and can also be set as a notch filter for chasing down problem feedback or rumble areas. Parametric midrange covers from 70Hz all the way to 8KHz, and fixed low and high controls are carefully voiced for musical shading of bass and treble.

ALiX

This is the little nipper, but don’t judge – we piled up everything we know from 30 years of designing mic preamps, zapped it with our shrink ray and crammed it all into a minty-fresh green BIX style chassis. With bonafide Grace Design mic preamp pedigree, it will give any studio rack preamp a run for its money. But REX is really designed to be velcroed to a pedal board and hit the stage. Simple high and low tone controls, a 10dB boost circuit (sorry FOH), a mute switch, and an FX loop will all help you get your sound dialed. Are you a singer with your own vocal mic and wish you could have that extra studio clarity and presence on stage? REX to the REXcue (ugh). You get the idea.
