The Fire Custom Shop Bass Pusher Preamp is an analog preamp pedal for bass, filed by its maker under overdrive, booster and preamp. RockBoard's PedalPedia describes its purpose plainly: "The main objective of the Bass Pusher is to give more body, presence and quality to the bass sound."1
It works as a pre-amplification system that filters and treats the instrument's signal while, in the maker's words, "preserving the integrity" of the bass's timbre. Controls cover bass and treble equalization plus a dedicated "Pusher" control, which is where the pedal gets its name.1
What it does
The Bass Pusher sits between your bass and the rest of the chain and shapes the signal before it reaches an amp or recording rig. The pre-amplification stage filters and treats the incoming signal, and the bass and treble controls let you add or cut low and high content around it. The Pusher control is the pedal's signature feature, aimed at pushing the sound forward with more body and presence.1
For players comparing preamp-style pedals, it sits in the same family as other preamp pedals, and its overdrive and booster classification means it can also be used to add gain and level rather than only tone shaping. Fire Custom Shop also makes the Little Boy, another pedal in the company's range.1
Power and practical notes
The pedal runs on a 9V DC, center negative supply and draws 3mA, a very light load that any standard isolated pedalboard supply can handle.1
Fire Custom Shop publishes a manual for the Bass Pusher Preamp as a PDF on its own site, which covers the pedal's operation in the maker's own words.1

Questions
Is the Bass Pusher Preamp analog or digital?
The Bass Pusher Preamp is an analog circuit, according to Fire Custom Shop's product listing. That matters for players who want the pedal to sit in an analog signal path, and it also means there is no digital conversion or latency involved in how it treats the bass signal.
How much power does the Bass Pusher Preamp need?
Fire Custom Shop specifies a 9V DC, center negative supply with a current draw of 3mA. That is a light load by pedal standards, so it is easy on a power supply, though the listing does not mention battery operation, so a DC supply is the way to plan for it.
