The Joyo JF-309 Boogie Master is a compact preamp pedal from Joyo, described by the maker as an amp simulator pedal that "brings you modern rock and metal sounds reminiscent of the leading company in the field"1. In other words, it is built to approximate the high-gain character associated with Mesa/Boogie amplifiers, in a stompbox small enough for any pedalboard.
Joyo says of its character that "the sound is always fat and always huge"1. The pedal is designed to work in three ways: directly into a mixing console, into an audio interface, or in front of a conventional amp1.
Power and connections
The Boogie Master runs on a DC 9V adapter and draws 25 mA1. That is a low enough draw to share an isolated power supply output with other small pedals, though Joyo specifies adapter power only.
Joyo lists no battery option for the JF-309, so it needs a 9V DC supply on the board.
On the connection side, the pedal presents a 1M Ohm input impedance and a 10K Ohm output impedance1. The 1M Ohm input is the standard value for a guitar amp front end, so passive pickups load the way they would into an amp. Because Joyo rates it for direct use into a mixing console or audio interface, it can serve as a recording or fly-rig preamp without an amplifier in the chain1.
Where it sits in the Joyo range
The Boogie Master is one of several amp-simulation pedals in Joyo's lineup. Players comparing options can also look at the Joyo JF-307, the Joyo JF-310, the Joyo Rushing Train, and the multi-model Joyo Preamp House and Joyo R-15, which pack several preamp models into one unit.

Yes. Joyo states the Boogie Master can be used directly into a mixing console or audio interface, as well as in front of an amp. That makes it usable for recording or silent practice setups without a guitar amplifier.
Does the Joyo Boogie Master take a battery?
No. The pedal is powered by a DC 9V adapter only, with a running current of 25 mA. Joyo lists no battery option for the JF-309.
What amp is the Joyo Boogie Master based on?
Joyo does not name the amp directly. The product page describes the Boogie Master as an amp simulator that delivers modern rock and metal sounds reminiscent of the leading company in the field, a widely understood reference to Mesa/Boogie.
