Description:
When designing the temperature controlled fuzz, we tried some weird approaches. One of the things we tried was utilizing a voltage controlled error correcting circuit to bias a single germanium transistor. It ultimately didn’t work for the fuzz, since that circuit is comically sensitive to transistor gain attributes.
We did find a place for it though.
It turns out it was PERFECT for achieving a germanium clean boost that, (like our fuzz) is impervious to component drift, leakage, and temperature....moreso in fact. We also fixed a couple other issues preventing the germanium transistor from being used as a convincing linear boost...we increased the input headroom (even a normal guitar signal will drive a germanium transistor into unwanted input distortion without some tweaks) and increased the input impedance (a BJT transistor would normally thin out bass frequencies and interact neg- atively with whatever flows into it).
The result is a germanium clean boost where you can utilize a germanium transistor WITH- OUT the weird artifacts that were previously accepted as part of the deal...temperature sen- sitivity, drift, and suboptimal input impedance and headroom.
It takes about 10 seconds when the boost is first powered up for the error correction circuit to bias the germanium transistor. After that it gets interesting....we can hear how it makes guitar signals sound more musical...even when set at the same volume as the bypassed tone. It seems to bring out the attack of the guitar while simultaneously smoothing out notes, like a compressor but different. It’s hard to describe. It appears to cut the bad parts of a signal and enhance the good. It’s killer on bass. It helps acoustic guitar pickups sound more natu- ral. And of course it’ll push your amp into a frenzy.
We hope you like it.
POWER SUPPLY
This pedal is for use only with a 9vdc Boss syle center negative power supply. There is space for a battery which is activated when a cable is plugged into the input, and there is no power supply plugged into the DC jack.
Please do not subject this pedal to more than 9vdc or the pedal or power supply could be destroyed.
WARRANTY INFORMATION:
2 years excluding modification or damage. Visit www.bensonamps.com for more information.

Good quality and helpful even if your dog doesn’t use it yet
Color: Gray, Color: Gray
Still hoping my dog will decide to use this, but even if not, it’s serving a useful purpose. I keep pee pads down for accidents, and I started by placing this on top to encourage my dog to use it instead. Right now, I have it next to our end table to protect it, and it fits perfectly there. I may try putting a pad on top to help with the transition. The quality feels decent for the price—the plastic is thick enough, looks nice, and the top stays in place without being difficult to remove. It’s practical, easy to clean, and works well for what I needed.

The Best Interactive Dog Toy My Dogs Won’t Put Down!
Color: Blue
I have a Labrador and a Jack Russell and I bought this Qraxond interactive ball mainly for my Lab’s strong hunting instinct but I was absolutely blown away by how both dogs went crazy for it. This toy isn’t just fun it’s a total game changer for keeping pups entertained stimulated and out of trouble when I’m busy.
The ball arrived nicely packaged with clear easy to follow instructions. It comes with a USB C charging cable for the internal motor no wall adapter included but any standard USB plug works perfectly. The bright blue color is such a smart choice it stands out everywhere so I never lose it in the yard carpet or under furniture.
Operation is incredibly simple. The inner vibration module is held securely in the ball with heavy duty velcro. Inside a rubber core vibrates and makes the whole ball move and bounce unpredictably. There’s a protective plastic flap covering the charging port just press the button once for low mode again for high active mode and a third time to power off. Super intuitive for anyone to use.
The build quality is solid. While it’s not designed for aggressive chewers and the seller clearly states that which I really appreciate it holds up amazingly well for normal play. My dogs love shaking it tossing it and playing tug of war with me and each other and the toy hasn’t shown any signs of weakening. The reinforced fabric loops are stitched tightly and make it easy for dogs to grab shake and carry even my Lab has a blast tugging on it and the vibration keeps him distracted from pulling too hard.
The motion activated vibration works incredibly well. It’s highly sensitive so it activates as soon as your dog paws nudges or moves it then shuts off automatically when play stops to save battery. Both speed modes are a hit the low setting is gentle but engaging and the high setting gets them zooming around. The random movement triggers their natural prey drive so they can play independently for 10 to 20 minutes straight something my people focused standard poodle rarely does without human interaction. It’s fantastic mental stimulation that tires them out without me having to throw a ball a hundred times.
It’s truly versatile for all dog sizes and breeds you can’t get more different than a Labrador and a Jack Russell yet both adore it. I ended up buying a second one just to stop them from fighting over it! The soft padded outer cover is gentle on teeth and gums and since the instructions note to remove the inner core before cleaning the cover is clearly machine washable making cleanup a breeze.
Battery life is impressive it lasts through multiple play sessions before needing a charge and USB C charging is as convenient as charging a phone. At under $25 this toy offers incredible value way better than similar products I’ve tried that cost twice as much.
If you’re tired of boring toys that get ignored or need a way to keep your dog busy and mentally stimulated while you work or relax this Qraxond interactive ball is a must have. It’s durable fun easy to use and loved by every dog I’ve seen play with it. Highly highly recommend one of the best pet purchases I’ve ever made!

My dogs love this ball
Color: Blue
This interactive dog ball has been a huge hit with my doodles — Simba, Roxy, and Ozzy! The second I turn it on, they go crazy chasing it around the house. It keeps them entertained, active, and mentally stimulated, especially on rainy days when they can’t burn energy outside.
I love that it moves on its own and keeps them engaged without getting bored after 5 minutes like most toys. It’s durable enough for energetic dogs and rechargeable, which is a huge plus. Definitely worth it if you have playful pups that need extra stimulation and exercise!

The dog likes it, til her short attention span kicks in
Color: Green
This is an interesting toy.
Our little doodle really likes it when it starts up. She does lose interest after about 30 seconds. I think it's the pauses in-between the 10 second Normal or Crazy Bouncing Mode.
When she does play with it she is intense about it.
The loopy handles are very handy.
The company stands behind the product.
I would buy it again.

A favorite toy in our house!
Color: Blue
This is the best interactive ball ever! It combines two of my pups' favorite toys...a soccer ball and weighted moveable ball. Perfect independent toy! We've had it for a few weeks and I've only had to charge it once. Amazing battery life.
