The JOYO JF-332 MOONBASE is a bass overdrive pedal from JOYO, built to add drive to a bass signal with a small amount of fuzz mixed in. JOYO describes its character plainly: "With its thick and rich tone, a tiny bit of fuzz will warm your sound." The maker positions it away from aggressive drive tones, saying it is "specially designed for JAZZ, BLUES and the other more subtle styles."1
What it does to a bass tone
The Moonbase sits in JOYO's bass line as an overdrive with a fuzz flavor rather than a straight distortion. The maker's own description of a thick, rich tone with "a tiny bit of fuzz" points to a mild, warm drive for players who want grit without losing the fundamental note, and the intended styles of jazz and blues match that brief.1
For a player comparing it within JOYO's own range, the Moonbase is the subtle end of the maker's bass drive options. Other JOYO bass pedals cover different ground: the Joyo Tidal Wave Preamp is a preamp pedal, the Joyo Double Thruster is a bass distortion, and the Joyo Scylla is a compressor. JOYO also makes the Joyo Dr.J Soloman Bass Overdrive, another overdrive in the maker's catalog.1
Power and connections
The Moonbase runs from a DC 9V adapter and draws 16mA while running, according to JOYO's product page. That current draw is light enough that it fits comfortably on a pedalboard supply alongside other pedals. The maker lists an input impedance of 1M Ohm and an output impedance of 100 Ohm.1
Size and weight
The pedal's small footprint is one of its practical points. JOYO gives its dimensions as 73(L) x 43(W) x 50(H) mm and its weight as 220 g, so it takes up little more room on a board than a standard compact enclosure.1

Questions
What power supply does the JOYO Moonbase use?
JOYO specifies a DC 9V adapter for the Moonbase. As with most compact pedals, a center-negative 9V supply of the standard pedalboard type is what the specification refers to, and the maker's product page lists no battery option. Use a supply with enough spare current for the pedal's 16mA running current.
How much current does the JOYO JF-332 Moonbase draw?
The Moonbase draws 16mA while running, according to JOYO's product page. That is a light load by pedal standards, so nearly any 9V pedal supply or daisy-chain output with headroom can handle it alongside other pedals.
What styles is the JOYO Moonbase meant for?
JOYO describes the Moonbase as specially designed for jazz, blues and other more subtle styles. The maker positions its sound as thick and rich, with a tiny bit of fuzz to warm the tone, rather than an aggressive high-gain drive.
What are the input and output impedances of the Moonbase?
JOYO lists the input impedance at 1M Ohm and the output impedance at 100 Ohm. The 1M Ohm input is the usual figure for a pedal designed to accept a bass's passive signal without loading it.
