Joyo JF12 Guitar Effects Pedal - Voodoo Octave

Take your tone an octave up and why not add some fuzz too!? This is a great sounding Octaver and Fuzz pedal in one. Joyo has put some nice features in their Ultimate Octave. It can be run strictly as a Fuzz box, which has controls for the amount of Fuzz and Tone, along with a Normal or "Mid Cut" toggle switch. Then, there is an additional switch where you can add an Octave up, which conjures up those Octavia type of tones. A mid-cut switch gives you control over your tone. Watch what happens when you put some fuzz on your chops, and then take it up an octave.

True bypass design minimizes tone loss and the super tough aluminium alloy casing will last for years.

And the voodoo is no different they sound great and you can get some serious grindage effects with a tweak or that perfect vintage type rock sound your chasing. I implore you guys to get out there a nd give one a go an exellent add on to your pedal board. Cheers artist for another great product John driver

It looks evil, it sounds killer, the mid-cut switch is awesome, and it's as cheap as chips. A welcome addition to my arsenal of noise machines.

Cool pedal but issues

By: on 1 April 2022
Sounds good and solid for the price but the 9v power supply on mine seems faulty, when I use it a harsh high pitched buzz occurs, I tried using a battery which fixed the problem but the battery won’t actually fit inside the pedal, disappointed.

I was looking for some specific sounds- high gain Pumpkins lead sound- think Gish. Well it’s all on this and a lot more. Stoked!

Voodoo Octave..

This pedal i have just found out makes a really good fuzz bass also. I think this is where the ' mid cut ' toggle comes into it's own.

Thanks Artist/joyo

This my favourite pedal. Plenty of fun. The fuzz dialed back is even a good distortion on it's own. Mid cut and octave shifter are bonuses. Great sounding fuzz. Backed it up with joyo Vintage Overdrive and together are very good combo with heaps of punch.

Great Fuzz Pedal

By: on 2 April 2019
Been using mine for a couple of years now and ive tested this against my EHX BIG MUFF and i can't hear any difference in tone quality which is crazy considering the price difference. Plus it even has extra features.

this pedal puts a big smile on my face, I've never had a fuzz before and this of the chart then I hit the octave up switch and there's that SRV/Hendrix lead tone. great product and well made.

Fantastic Fuzz

By: on 28 May 2016
This pedal transports you back to the 60s. The glorious sound of Hendrix and the Beatles. What a sound. This is a seriously good pedal, great sound and adjustability. The octave is a little weak, but for the price it is more than acceptable. Another cracking Joyo product. Don't worry about the name just buy and try. Ian Western Australia

if you like jimmy hendricks then this will get you that sound. I have bought 3 joyo products and 2 from artists guitars, fast post and honest dealers. Joyo products are inexpensive and high quality. Thanks again Artists guitars
