This pedal was gifted to me on Christmas and I've been using it since the day I got it. There is a set high and low octave as well as a dry signal control. You can control how much of the High/Low octave you want in the signal. I often use this pedal with a Graphic EQ to emulate a Bass guitar and it does the job well. I personally would recommend buying this pedal.
For under $50, it’s a good deal
I was pleasantly surprised by this octave pedal. It produces nice punchy and tight octave sounds that are rather quick for a cheaper octave pedal. It does has a minuscule amount of latency but definitely usable. Sounds better than the octave effects on my Boss GT-8. It’s nice having separate mix controls for the higher and the lower octaves. The high octave gets a little wavy sometimes but that low octave is spot on, even being placed after a few drive pedals for fun.
