This thing is wild. It has two lower and two upper octaves, plus the ability to save 8 different settings and switch between them while performing. It also has a true bypass that adds zero noise when the pedal is not being used. I bought this to add some bass riffs while looping during practice sessions. Mission accomplished. The lower octaves are perfect for that. The upper octaves were just a bonus and they can be subtle or cranked up to sound like an organ accompanying you. There is zero delay/latency in all 4 octaves; this thing keeps up even with hammering those 64th notes. It's worth mentioning that I have my pedal board routed to BOTH a 2x12 inch guitar amp and an 18 inch bass amp. The low octaves are sweet through the bass amp while the guitar amp picks up the rest. If you don't have a bass amp or otherwise some way to amplify the lower octaves, then you might not have the same experience. This pedal is five stars for performance capabilities, it sounds great. My only complaint is that it feels a little flimsy. All of my other pedals I feel like I could throw them down the stairs, plug them back in and keep going. The POG2 doesn't feel like that. It feels like I could break the faders or stomp the buttons through the box if I really smash them. I'm generally pretty calm while playing though, so I don't believe it will be an issue for me. But it's noticably lighter and thinner metal than my other pedals. All in all I'm happy I bought this pedal. It can make some really cool noises when engaged.
