I bought Joyo Voodoo Octave Fuzz recently. What an awesome pedal it is for a ridiculous price (30 new). I bought mine used and paid 25 including shipping.

You know that pedal is great when it really inspires you... Made these two pieces and and recorded them pretty much out of the blue, simply due to those tones. These are with Fuzz knob around 8 o'clock, so there some real sonic annihilation available from that pedal.

I'm happy with these tones. It even works brilliantly to straight up dirty amp. (These are not done with perfectly clean amp either tough.)
