The JOYO JF-330 OCHO is an octave pedal from Joyo, a compact stompbox that adds octave voices to your guitar signal. Joyo describes it as a pedal where "you can dive into wide and rich sound textures that make your guitar sound larger than life!"1. It sits in the wider family of octave and pitch pedals, a category that also includes Joyo's own Joyo R-13 XVI polyphonic octave pedal.
Controls
The Ocho keeps things simple with three knobs:
| Control | What it does |
|---|---|
| OCT1 | Sets the level of the first octave voice |
| OCT2 | Sets the level of the second octave voice |
| LEVEL | Sets the overall volume |
Joyo's product page explains that "you can control the level of both octaves with the OCT1 and OCT2 knobs and the overall volume with the LEVEL knob"1. In practice, that means you blend the two octave voices against each other and against your dry signal path, then set the pedal's overall output with LEVEL.
Power and bypass
The Ocho runs on a DC 9V adapter and draws 20mA of running current1. That is a modest draw, well within what a typical pedalboard power supply output provides, but the pedal is designed for adapter power rather than a battery.
Joyo specifies a DC 9V adapter for the Ocho, so make sure your power supply output can deliver at least 20mA at 9V1.
For switching, Joyo states that "as most of our pedals, the Ocho is also True Bypass"1. With true bypass, the pedal is removed from your signal chain entirely when it is off, which matters if you run long cable runs or many pedals.
The pedal's input impedance is 1M Ohm and its output impedance is 100 Ohm1, standard figures for a pedal placed at the front of a signal chain.
Size and weight
The Ocho is a compact pedal. JOYO lists it in its JF series as the JF-330, an octave pedal with a small footprint that leaves room on a pedalboard for more effects1.
Where it sits in Joyo's range
Joyo lists the Ocho in its JF series as an octave pedal, with the octave effect as its whole job rather than one mode among several1. The maker describes it as a pedal for diving into "wide and rich sound textures that make your guitar sound larger than life"1. Within Joyo's range it is the straightforward octave option: two knobs, an octave blend, and nothing else on the face of the pedal to set.

Questions
Is the JOYO JF-330 OCHO true bypass?
Yes. Joyo says that, as with most of its pedals, the Ocho is true bypass, so when the pedal is off your guitar's signal passes straight through to the amp without going through the octave circuit.
What power supply does the JOYO OCHO use?
The Ocho runs on a DC 9V adapter. There is no mention of battery operation, so plan on a 9V DC center-negative supply or a spare output on your pedalboard power supply.
How much current does the JOYO OCHO draw?
Joyo lists the running current at 20mA, which is a light load that any standard 9V pedalboard power supply output can handle.
What do the OCT1 and OCT2 knobs do?
The OCT1 and OCT2 knobs control the level of the two octave voices, letting you set how much of each octave sits in the mix. The LEVEL knob sets the overall volume of the pedal's output.
How big is the JOYO JF-330 OCHO?
Joyo lists the Ocho at 73mm long, 43mm wide and 50mm high, weighing 220g. That is a compact footprint that fits easily on a crowded pedalboard.
