The BiX from Grace Design is a floor-mounted preamp intended for use with acoustic instruments. It features many of the same audio-performance benchmarks of its bigger siblings—the FELiX and the AliX—though with a streamlined layout of controls. You'll find four knobs on the preamp, which allow you to set the gain, shape the EQ of your instrument, and dictate a level for boosting signal. To instantiate this boost, a footswitch is provided, giving you the ability to add up to 10 dB of gain to your signal. The other footswitch mutes the BiX.

On the rear of the unit you'll find a 1/4" input, two additional 1/4" jacks for patching in an effects loop, an unbalanced 1/4" output, and a transformer-balanced XLR DI output for use with mixers, PAs, or recording devices. You'll also find a 9V power jack. Made in the USA, this preamp should fit into your pedalboard with ease.
