The 4000PRE is a compact booster pedal from Nature Sound that covers three jobs at once: it is described by the maker as a "BUFFER BOOSTER PREAMP", so it can drive a long pedal chain, lift a signal into an amp or front end, and act as a small preamp in its own right. It sits in the preamp and boost territory of a board, and its buffer role also places it among buffer pedals.1
Nature Sound calls it its "latest minimum sized booster pedal", and the circuit is analog. The stated design goal is a familiar one to studio players: "We aimed to bring back the sound of world famous large console. This console is used in many studios worldwide, so many" performances were recorded through its head amp. In plain terms, the maker is chasing the coloration of a classic recording console's input stage rather than a flat, transparent boost.1
What it does for a player
Because the 4000PRE combines a buffer, a boost and a preamp in one small enclosure, it can serve several places on a board: at the end of a chain to keep the signal strong, before an amp to push it, or as a always-on tone shaper. Nature Sound says the pedal suits "not only the electric guitars but the acoustic guitars and the bass guitars", with a broadened dynamic range and smooth frequency characteristics. That makes it a candidate for players who run multiple instruments through one board, including bassists looking at bass pedals.1
