SO the "Fire" makes sense, though as a name for musical gear, not so much.
I still have a Vesta Fire 4 track recorder that uses those big rattly cartridge things that the cavemen had back before SD cards, with the two little fear shaped wheel thingies... whatever they were called...
When the knobs are set just exactly right, it can produce the most awesome bass distortion ever heard. Really tough to find that sweet spot though. It's been very dependable ever since I bought it, back in the Pleistocene when it was new.
Assuming the preamp works, and I'd think that given the store's rep it would, I wouldn't worry about reliability. No idea what it actually sounds like though.
