No Taxes, Duties, Tariffs - Fast Free Shipping - Free Returns: $269 is your absolute final/total cost here for the Ground FX Koloss Muff pedal.

Handmade in Hamburg Germany, the Ground FX Koloss is not a replica of any existing Muff. Apart from an additional mid-pot that interacts with the tone-pot, you‘ll also have a saturation control, a very nice feature that controls the fatness of the Koloss pedal.

All Muffs out there have two gain stages. Some of these Muffs allow a different clipping in the second stage. But Ground FX didn't like these clipping options available via toggle, so they decided to add a third gain stage, that can be activated via footswitch.




The first two gain stages are based on SI-diodes, and produce very doomy and gnarly distortion/fuzz sounds. The third stage brings in some GE-diodes into the circuit. Expect pure thickness and a lot of deep, low end from the Koloss!

Koloss is a perfect pedal for bassists as well. That's why Ground FX integrated an active blend circuit to mix the dry and wet signal... ideal for bass players too!

CONTROLS:
Tone, Mid, Gain, Saturation, Blend, and Volume.

FEATURES:
  • True Bypass - when the pedal is off, your signal is untouched.
  • Relay Switching - the newest kind of switching, with less noise.
  • High Quality Clickless Switches - no loud click to turn it on/off.
  • Silver Sparkle Enclosure - perfect look for the Ground FX deep, dark sounds.

This pedal does not use a battery

Best ball toy I have found
Size: Small
This is my dog’s absolute favorite. I bought this one as a replacement. Finally after years of use one of the tiny ribs gave way. Ball is still completely useable, but got another. She chomps down on it constantly, tears at it, shakes it in her mouth. It is extremely durable. One of the great things about this ball is how ‘soft’ it is. Meaning the way it’s constructed makes it have a lot of give. The texture of the ball itself is firm, but the amount of ‘airiness’ means you can throw it inside your home, against walls, furniture, etc without worrying about any damage. Great toy inside and outside. Highly recommended ball toy. They make all different sizes. My dog is 25 lbs and loves both the 3” and the mini. The mini ones are the same size as mini tennis balls..problem is she would destroy a mini tennis ball within a day of getting one. She has had the mini Hol-ee Roller for years. Super durable.

I have a toy dog and she really loves this
Size: Small
however her mouth is very small and she had a difficult time gripping the ball. so I took a pair of scissors and cut out a section to make a bigger hole for her to get her little mouth through and now she has a lot of fun picking it up and playing with it. The ball is well-made and is one of her favorite toys. if I tell her to go get her ball she will even go under the bed and is able to grab it and carry it up the stairs to the bed for playtime. It also makes it easy when we are in the yard when I throw it. It is light enough for her to carry and bring back to me. But, as I said , I did have to adapt it so she could get a grip.

Easy to grab and throw!
Size: Medium
Our puppy loves this ball, although it gets stuck on her teeth sometimes, but she gets it off just fine! Easy to play and throw. She has a blast catching it, too!

Keeps my dog happy
Size: Medium
This is a fun toy for our cavalier. It's pretty versatile in how you can use it, which I like because it allows me to change things up to keep my dog engaged. He's also an aggressive chewer and he hasn't destroyed it.
