New Systems Instruments Quad LFO Phase X ExpanderUnlock the potential of the Quad LFO with the LFO Phase Expander. Each expander gives you three outputs that duplicate the LFO with a fixed phase difference. The first ranges from 0 to 180, the second from 90 to 270, and the last from 180 to 360. Along with the original output, this gives you four phases of modulation. These are easily tuneable to quadrature (all knobs centred), but also any arbitrary phase relationship. You can attach up to four

My Blue Heeler tears up almost all of her toys if they’re not rubber. This ball is SO durable and she loves it so much!! We’ve had it for 5 months now. She chews on it every day for long periods of time and it’s showing pretty much no wear and tear. I keep wondering if I’ll ever have to pull out the second one from the box lol. It can be hard to squeak with one hand, but it’s easy enough with 2 hands or if you step on it with your foot. It’s hilarious that every time I squeak it she licks her lips. My girl never actually squeaks it while she’s chewing on it, which is actually a plus cuz it doesn’t get annoying when she’s chewing on it for long periods of time. I also love that the ball helps clean her teeth because of the spikes and the size is larger so it’s easy to take it from her while playing fetch. Overall a fun, durable dog toy!

Totally indestructible!

Color: Purple, Color: Purple

Finally! A toy my aggressive chewer cannot destroy!! Can’t even get the squeaker out! No other toy has ever held up and it’s got some nice bounce to it. Perfect size so it can’t get stuck under the sofa. Furthermore, it aids in cleaning his teeth and he loves them. This is a great money saver too! Update - 3 months later - still pup’s fav…still whole - still lotsa bounce - still has squeaker intact. As good as new! I’d buy these again but don’t need to 😃!

Toughest ball of this type.

Color: Blue

My dogs are brutal with these toys. I really like them as the spikes act as a tooth brush, and the dogs love knawing on them. There are other spiked balls like this on amazon, but this one is of better quality. It lasts a lot longer. The squeaker does not last long, the dogs teeth push it into the ball, you can hear it rattling around in there.

Very good for aggressive chewers

Color: Red, Blue, Green, Yellow

Finally found ball that my aggressive chewer doesn't destroy. Has loud squeaker however he broke after 4 days. Probably better, noise gone. Very sturdy and he loves. Also big so doesn't roll under furniture.

Durable

I bought this for my 80lb 1yr American Bully male,who has made it his mission to test all the toys his dad and I have bought. Now I have 3 other American Bullies, siblings 3yr old 2 females/1male, who did the same at that age and I mastered toy shopping or so I thought. Lol. My new pup loves balls and this is the only one he firstly can't fit completely in his mouth and can't tear it apart. He has tired!
