Grace Design Felix 2 BK

A Stage Preamp Continuing Grace Design's "Pro Audio" DNA

The Grace Design FELIX 2 follows in the footsteps of equipment renowned for transparency, reliability, and manufacturing excellence. Designed in a compact and rugged pedalboard format, it has a clear goal: to offer preamplification and mixing worthy of a studio environment, but with the ergonomics, durability, and quick adjustment capabilities essential for live performance.

This FELIX 2 version focuses on the practical needs of acoustic instrumentalists and technicians: modern management of multi-source configurations, a truly usable stereo approach on a pedalboard, and finer correction tools to maintain control in resonant rooms or noisy stages.

A Premium Control Center for Demanding Acoustic Instrumentalists

The FELIX 2 is aimed at musicians who want to get the best out of an acoustic guitar, violin, viola, cello, double bass, mandolin (and more broadly any string source), whether in rehearsal, studio, but especially live. It is particularly relevant if you switch between a pickup and a microphone, need to manage two sources, or seek a highly qualitative solution for an acoustic set where grain precision and dynamics make all the difference.

On a pedalboard, it can act as a "hub": you prepare your sound, manage your effects, then send a clean and controlled signal to your stage amplification. In professional contexts (venue, FOH, stage), its 2-channel approach and correction tools also facilitate instrument changes and quick adaptations to the room's acoustics.

Stereo, Effects Loops, and Variable Phase: A FELIX Designed for Modern Setups

The standout new feature of the FELIX 2 is its stereo operation. The dual effects loop can be used in two ways: as independent loops per channel (convenient for separately processing a mic and a pickup, or two instruments), or as a true stereo effects chain with mono or stereo input. The result: you can maintain a coherent stereo image, whether for modulations, delays, reverbs, or more immersive spatial processing.

Channel 2 additionally includes a variable phase control. This is a decisive advantage whenever you combine multiple sources (mic and pickup, two pickups, two mic positions, etc.): by adjusting alignment, you avoid frequency dips, regain a more stable low end and clearer attack, and achieve a more "focused" mix. In practice, this kind of adjustment transforms a merely adequate sound into a solid, precise, and musical one, especially on instruments sensitive to phase interactions.

Regarding equalization, the focus is on effectiveness in real conditions. The high frequencies gain flexibility thanks to a selectable transition frequency (1 kHz or 2 kHz), helping to adjust presence and articulation without unnecessarily harshening the top end. The Notch filter, with a higher Q setting, allows for more precise targeting of problematic frequencies: ideal for treating body resonances or feedback onset with a more "surgical" correction, while preserving the instrument's natural character.

The Sound

The Grace Design FELIX 2 favors a clean, detailed, and dynamic reproduction, designed to respect the attack, nuance, and personality of the instrument. Its approach is that of a "faithful" preamp: the playing feel remains intact, and the sound retains an organic quality, without artificial compression or excessive coloration.

The EQ and Notch have a very musical purpose but are precise enough for "corrective" use when the stage imposes constraints. Combined with the variable phase on channel 2, the FELIX 2 helps achieve a more coherent signal when blending mic and pickup: the low end often becomes firmer, the midrange more stable, and overall definition clearer, resulting in a sound that sits better in the mix at equal stage volume.
