Description
This is the little nipper, but don’t judge – Grace Design piled up everything they know from 30 years of designing mic preamps, zapped it with a 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.
Features:
- Mic input (only) with 48V phantom power
- Switchable 75Hz High Pass Filter
- High and Low shelving EQ
- FX loop with individual send and return jacks
- Variable boost circuit
- Mute switch
- ¼ in unbalanced output / XLR balanced ISO output
- 9VDC power supply
Why a MIC PREAMP pedal?
Singers
A singer can plug their favorite microphone into a Grace Design mic preamp with their own effect pedals in the FX loop and control their reverb, old-timey AM radio or distorted vocal effects however they want. Singers with pedal boards? Your time has come.
Horn Players
Horn players looking to expand their sonic palette. Flugelhorn into a wha-wha pedal with distortion and delay? All day. Baritone sax through an octave pedal? Dude.
In the Studio
Recording engineers can harness the creative possibilities in the studio by inserting various guitar effect pedals into their recording signal chain. The possibilities are vast.
Acoustic Music
Hardworking one-mic bluegrass bands with their very own high-fidelity Grace Design mic preamp on stage. If the banjo and bass player get in a fight, someone can please just tap the mute switch while they sort it out. Embarrassing situation averted.
Creative Souls
Any sonic explorer looking to add a single channel of Grace Design preamp to their kit with some unexpectedly cool extra features. Nice.
