The MXR Poly Blue Octave brings modern and classic pitch shifting styles together with fuzz and modulation to create the ultimate octave pedal for tonecrafters and sonic seekers.Leveled up.
The Poly Blue Octave features four separate octave divisions—one octave down, two octaves down, one octave up, and two octaves up—and you get to control the level of each in the mix. Each is polyphonic by default, which means they sound just as amazing with chords as they do with single note passages. Your dry signal gets its own level control, as well, so you can dial in the perfect blend of pitch-shifted tones.
From contemporary clarity to raw vintage grit.
The Mono switch takes you back to the gritty, monophonic tones of analog style pitch shifters. In this mode, the sub-octave signals have the warm vibes and raw personality of a pedal such as the MXR Vintage Bass Octave, while the higher octave signals resemble the Octavio Fuzz with its fuzz intensity dialed all the way back.
Call up the thunder and lightning.
The Poly Blue Octave comes equipped with an unruly fuzz that’s inspired by the classic MXR Blue Box™ Fuzz. Applied to all five signals, the fuzz volume can be adjusted using the Dry knob after pressing and holding the Fuzz button. When used with the sub-octave signals, the fuzz sounds thick and subterranean. Over the higher pitched signals, the fuzz is searing and synth-like. Run them all at the same time for a choir of thunder and lightning.
Phase yourself.
For infusing your octave tones with an alluring sense of motion, from thick and syrupy to frenzied and frantic, the Poly Blue Octave features a dual-mode modulation circuit. In polyphonic mode, the circuit provides an uncanny simulation of the famous Leslie effect, and while in monophonic mode, it provides classic swirls and swooshes inspired by the Phase 90. Like the fuzz effect, the modulation applies to all five signals when engaged. The Mod knob adjusts the rate of the effect—when you want it off, just roll the Mod knob back fully counterclockwise.
Step up and take control.
Through the EXP jack, the Poly Blue Octave allows you to control various settings with an expression pedal such as the Volume (X)™8 Pedal or an off-board switch such as the MXR Tap Tempo Switch to sweep between two different knob and switch configurations or toggle the fuzz and mono modes on and off.
A full palette of tones and textures in a single pedal.
The MXR Poly Blue Octave delivers high-performance pitch shifting, fuzz, and modulation in a ruggedly reliable housing with true bypass switching. Put this into your signal chain, and open up new sonic frontiers.

Low/mid-tier toy at a high price point
Color: YELLOW
I have two pitbulls and they LOVE their babies! Sadly, one of them likes to tear their babies apart when he gets anxious, so it was time to look for some new ones. They seem to favor any stuffed animal can be "nommed" on (suckled), so when I came across this duck rope toy, I thought I'd give it a try!
The toy arrived quickly, did not have any visible defects, and looked exactly as it does in the listing photos. It has a body filled with stuffing, crinkly arms, and a rope neck. There is one squeaker in the main body section. The minute the dogs saw me unpack the duck, they were at my feet and staring at me like "hand over the baby, woman." So, I did.....
And they hated it :(
For some reason, my dogs have totally rejected this toy... All they do is sniff it? They typically LOVE rope toys or anything that is elongated and allows them to play tug-o-war. So, I am not sure what the deal is with this duck. *shrug*
Currently, this stuffed duck rope toy is listed for $10.49 on sale, down from the regular price of $14.99. I consider this toy to be low end to mid tier at best. It's something you would expect to find at your local discount/dollar store. Based on the lower quality, I think the current price is higher than I would be willing to pay for this toy. While the toy is exactly as depicted in the listing photos, it is nothing special and definitely is NOT "indestructible."

Durable and my pup loves it
Color: YELLOW, Color: YELLOW
My pup loves squeaky toys. The problem is she also likes to tear up the toy to get the squeaky out. Finding a toy that she enjoys and it have the durability to stand up to her is a challenge.
I decided to give the CJZJPV Plush goose a try and I’m glad I did.
She absolutely loves the toy and it has stood up to her chewing and shaking.
The thing I notice about many dog toys is there always seems to be a bad seam or weak spot in the toy. My pup will find this imperfection and go ahead to dismantle the toy.
The seams on the CJZJPV are done well and there are no protruding eyes or flaw for her to get her teeth into.
This is a good, durable dog toy.

A huge hit for the whole pack
Color: GREEN
Finding a toy that appeals to multiple dogs with different play styles is tough, but this interactive green goose is an absolute home run. The combination of the crinkle wings and the squeaker keeps them entertained and busy way longer than a standard plush toy.
Despite the daily thrashing, tugging, and chewing, the durability has been incredibly impressive. It’s the perfect size for larger breeds to grip, yet lightweight enough for smaller dogs to carry around by the neck.

Great toy that's a real hit so far!
Color: YELLOW
This squeaky goose has been a total hit and, more importantly, it actually passed the "German Shepherd test." It is always a gamble with plush toys and large breeds, but this one has stayed completely intact after several play sessions. Even with all the shaking and carrying around, the seams are holding up perfectly and the squeaker is still going strong. The combination of the squeak and the crinkle wings keeps things interesting, and the material feels much more durable than your average stuffed toy. If you have a powerful chewer who still loves a soft toy to carry around, this is a great, resilient option that won't fall apart immediately.

Great Bang for Your Buck
I didn’t know what to expect with these toys. How small are they, the quality, especially since they’re actually $1.33 each. I am so excited about these toys for my Havanese puppy! They’re a perfect size for him and they’re well sewn and cutely decorated. They’re stuffed and have a squeaker. He’s had one exactly like these for 2 months and he loves it and hasn’t torn it apart. When I saw the box delivered today I thought oh no these are so tiny. Until opened it and kept pulling perfect sized toys and a storage bag! These are just carefully and mindfully packed to fit in that box!
