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
, it uses a standard 9 Volt DC, Center-Negative power supply (like Boss and most all other guitar pedals use).

Worth it.
Size: 16 Fl Oz (Pack of 1), Style: Fresh
Love this products. Regret not getting this sooner or even the kit. But super good, and actually smells pretty good no harsh chemical smell. Removed any stained I had with such easy. Which made application easy, just spray on microfiber towel and wipe away. A little expensive but again my fault for not going with the kit.

It’s just a great cleaner no residue you don’t need a lot of it. No weird or funky stink to it. It just cleans.

Not effective as a cleaner
Size: 16 Fl Oz (Pack of 1), Style: Fresh
If you’re looking for a cleaner, this ain’t it. It’s about as effective as water on plastic.

Streak free and quick drying. Big and pricy but worth it.
Size: 1 Pack (24" x 36")
Great for drying off your car especially in places where the water pools. Streak free and covers a lot of area. It’s big and versatile- it would work as a pet drying towel too. Soft and good quality. Great gift for a car buff. Not cheap but man does it cut down on drying time.

Great size, super soft, and extremely efficient.
Size: 1 Pack (24" x 36")
Love this drying towel. It’s super soft, super efficient and cuts my dry time in half. The size is perfect for my car as it covers most of my roof making it really easy and quick to dry the whole car. It’s also super absorbent and definitely worth every penny.
