The Fxamps Bi Boost is a dual boost pedal designed for electric guitar, made by Fxamps. It belongs to the boost pedal family: pedals whose job is to raise the level of your signal rather than add distortion of their own. RockBoard's PedalPedia describes it as intended to increase signal level for solos, drive an amplifier harder, or shape overall dynamics1.
Its defining feature is that it carries two independent boost circuits. Those can be used separately or combined, so the pedal can act as a single boost, or as two stages of level that stack when both are engaged1.
What it does
A boost pedal sits in the signal chain and raises the level of whatever feeds it. RockBoard's PedalPedia describes the Bi Boost's intended uses in three ways: lifting the signal for solos, pushing an amplifier harder so it breaks up more, and shaping overall dynamics1. Because the circuit is analog1, the pedal works on the guitar's own signal rather than converting it to digital.
The two-circuit design is what separates the Bi Boost from a single-circuit boost. With two independent circuits, one can be set as a light lift for rhythm parts and the other as a bigger lift for leads, and both can be engaged together when a part needs the most level1.
The Bi Boost draws 100mA1, which is more than many simple boost pedals need. A low-output power supply output or a shared daisy chain may not be enough on its own.

Questions
What is the Fxamps Bi Boost used for?
It is a dual boost pedal for electric guitar. According to the maker, it is intended to increase signal level for solos, drive an amplifier harder, or shape overall dynamics. It carries two independent boost circuits, so you can run one boost alone, the other alone, or both at once.
Is the Fxamps Bi Boost analog or digital?
The Bi Boost is an analog pedal. It runs on a 9V DC, center negative supply and draws 100mA of current, which is worth keeping in mind when planning a power supply.
