Grace Design Felix Acoustic Instrument Preamp

The Grace Design Felix Acoustic Instrument Preamp is a studio quality 2-channel blending acoustic instrument and mic preamp, designed for working musicians, engineers, sound companies or venues looking for the highest quality solution for amplifying stringed instruments.

The Grace Design Felix Acoustic Instrument Preamp is built into a roadworthy (beer-resistant) floor unit chassis of anodized aluminum and steel, portable enough to leave the rack at home but bring studio quality to the stage. With the same stunning audio performance and legendary reliability as Grace Design’s pro audio range, the Grace Design FELiX brings open, musical and nuanced preamplification to any performance situation.

A powerful EQ section allows simple and intuitive tone shaping for even the most unruly of instruments. Each channel’s variable 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 mid range controls cover from 70Hz all the way to 8KHz. While fixed low and high controls are carefully voiced for musical shading of bass and treble.

Controls are simple and clearly marked on a bright panel, making them easy to read and tweak on a dark stage. Footswitch functions include a mute / tune switch for muting all outputs except the dedicated tuner out, a boost switch which activates a variable boost circuit, and finally, an A/B mode switch for when Grace Design FELiX is in A/B mode (which simply toggles between the two different channels).

The Grace Design FELiX brings the kitchen sink approach to I/O. Inputs include a 48V XLR mic input and two instrument inputs. Two independent transformer isolated DI outputs can be sourced from either the mix or the individual channel. This allows you to send the front of house a mix or each channel independently. A dedicated, level controlled amplifier output can be sourced from the mix or channel 2. A dedicated tuner output stays active when all the other outputs are muted. A side panel mounted 1/8” mini jack headphone amplifier is there for practicing, private noodling during boring soundchecks, or scrutinizing dubious eq decisions. A TRS insert is included for adding effects, and finally, a remote footswitch jack is included if the Grace Design FELiX is going to spend his life in a rack or up off the floor.

Guitar, bass, fiddle, mandolin, cello, dare they say banjo, that weird 3 string gourd thing – Grace Design FELiX is your instrument’s new best friend. Flexible, reliable, a good listener and eager to make you sound better, he is also your new best friend.
