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.

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

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.
