The JOYO JF-311 Blue Rain is an overdrive pedal from Joyo, a maker known for budget-friendly stompboxes. JOYO describes its character plainly: "The Blue Rain delivers a very warm and comfy overdrive tone. The absence of compression makes this pedal very open and honest."1 For a player, that means a drive that responds to your picking and your guitar's volume rather than smoothing everything out, in the territory covered by our Overdrive Pedals guide.
Tone and controls
JOYO's pitch for the Blue Rain centers on that lack of compression: the pedal leaves the dynamics of your playing intact instead of clamping them down, which is where the "open and honest" description comes from.1
The tone-shaping side is handled by two controls JOYO calls out specifically:
- HI and LOW controls, which JOYO says "give you a lot of options and help you adjust the pedal to your guitar and amp sound."1
That two-band approach to treble and bass, rather than a single tone knob, is what lets the pedal be dialed into a dark guitar or a bright amp without fighting either1.
Power and specifications
The Blue Rain runs from a DC 9V adapter and draws 10 mA, a small current draw that any standard pedalboard supply output can handle.1 Its input impedance is 1M Ohm and its output impedance is 10K Ohm, conventional figures for a drive pedal placed between guitar and amp.1

Questions
Does the JOYO JF-311 Blue Rain take a battery?
JOYO's product page lists the power requirement as a DC 9V adapter and does not list battery operation, so plan on running the Blue Rain from a 9V DC power supply rather than expecting an internal battery option.
What power supply does the Blue Rain need?
JOYO specifies a DC 9V adapter for the JF-311 Blue Rain. Its running current is low at 10 mA, so it sits comfortably on a pedalboard supply alongside other standard 9V pedals.
How much current does the JF-311 draw?
JOYO lists the running current of the JF-311 Blue Rain at 10 mA, a small draw by pedal standards that any standard 9V DC adapter or pedalboard power supply output can handle.
What are the input and output impedances of the JF-311?
JOYO gives the Blue Rain an input impedance of 1M Ohm and an output impedance of 10K Ohm. The high input impedance suits passive guitar pickups, and the low output impedance is typical for driving the next pedal or an amp input.
How big is the JOYO Blue Rain?
JOYO lists the Blue Rain's dimensions as 73 mm long, 43 mm wide and 50 mm high, with a weight of 220 g, making it a compact pedal that fits easily on a crowded board.
