The Joyo JF-24 Orthros Selector is a compact analog pedal from Joyo built around one idea: instead of one set of controls, it gives you two. The pedal allows you to switch between two channels, A and B, with separate gain, tone, and volume controls for each channel, so you can set up a clean sound and a driven sound and move between them with a stomp1. Joyo classifies it as a switcher and volume pedal, and it sits in the JF series of the company's compact pedal range12.
What it does for your sound
The Orthros Selector works as a two-channel preamp-style switcher. Each channel carries its own gain, tone and volume control, so the two sounds are set independently rather than being one tone with a boost stacked on it1. In practice that means channel A can hold a clean rhythm setting while channel B carries more gain for lead work, and the footswitch moves between them. Because the circuit is analog, the signal is not converted to digital on the way through1.
Joyo also lists the pedal under the volume category alongside switcher, which places it among tools for managing levels as well as tones1. It is a different kind of tool from a rocking-plate unit like the Ernie Ball VPJR or the Morley M2 Passive Volume: those sweep volume with your foot, while the JF-24 switches between two preset levels and tones.
Controls
| Control | What it does |
|---|---|
| Channel A gain | Sets the amount of drive on channel A |
| Channel A tone | Shapes the treble character of channel A |
| Channel A volume | Sets the output level of channel A |
| Channel B gain | Sets the amount of drive on channel B |
| Channel B tone | Shapes the treble character of channel B |
| Channel B volume | Sets the output level of channel B |
| Footswitch | Switches between channels A and B |
The two-channel arrangement, with separate gain, tone, and volume controls for each channel, is the pedal's defining feature as RockBoard's PedalPedia describes it1.
Power and current draw
The JF-24 runs from a 9V DC supply with a center negative plug and draws 22mA1. That is a light load by pedalboard standards, well within what any standard supply output handles.
The manual listed for the JF-24 is identified as a no-battery version, so the pedal is powered from an external 9V DC supply rather than an internal battery1.
Availability
Joyo's own product page for the JF-24 Orthros Selector shows stock at zero, so the pedal is not currently available directly from the maker's store2. The page also lists a retail price of 0.0 元 CNY, which appears to be a placeholder rather than an active price2.

Questions
Is the Joyo JF-24 Orthros Selector analog?
Yes. The JF-24 Orthros Selector uses an analog circuit, according to the pedal's specifications listed on RockBoard's PedalPedia. That means the signal passing through the pedal is handled as a continuous electrical signal rather than being converted to digital data, which is the usual arrangement for a simple two-channel gain and tone switcher like this one.
What power supply does the JF-24 Orthros Selector need?
The JF-24 runs on a 9V DC power supply with a center negative plug, the same standard used by most compact pedals. It draws 22mA of current, which is modest enough to sit comfortably on a shared daisy-chain or an isolated output of a typical pedalboard power supply.
Does the JF-24 take a battery?
The manual listed for the JF-24 is described as a no-battery version, which indicates the pedal is powered from an external 9V DC supply only and does not run on an internal battery. Plan to have a 9V DC center negative output available on your power supply.
How much current does the JF-24 draw?
The JF-24 Orthros Selector draws 22mA, according to its specifications on RockBoard's PedalPedia. That is a light current draw by pedal standards, so it adds little load to a pedalboard power supply and can share a supply output with other low-draw pedals.
