ALL SALES FINAL!

Heavy. Thick. Electric.

Many sounds have come and gone over the decades of electric guitar, but one sound in particular was born of fire and cemented in Rock N Roll: the Fuzz Sound.

Within the vast world of fuzz, few can claim the esteem, recording history and power of the classic IC (integrated circuit) distortion-sustainer of the late 1970’s, and there are sound reasons for this accomplishment: the thing circuit just plain rocks!

A fountain of inspiration and a highly effective tool, the SludgeMaster adds heaps of powerful, saturated intensity to your guitar (this thing absolutely RIPS on bass too), readily fattening up single-coils and driving humbuckers well into that “wall of sound” sound, transforming lead lines into “flaming flutes” and rhythms into an absolute tsunami of volatile melodic power.

When we designed the SludgeMaster, we didn’t just copy a thing. No, we saw how we could expand the ferocity, reduce the noise and sweeten up this literal classic, and boy howdy did we do it.

Everything in this pedal is all the way nice.

From tuning the the high-grade passives, to adding robust mechanicals and even down to the deliberate tracking of the circuit board, the SludgeMaster will shock you with its voracious appetite for mayhem and aggression.

Powered by either an internal 9V battery (not included) or “industry standard” 2.1mm negative center-pin 9VDC pedal power, the SludgeMaster delicately sips just shy of 9mA but what it does with that nominal current is downright shocking!

We recommend that you play this pedal at the highest possible volume level attainable with your rig. Get loud and get after it.

  • Classic 100% analog, high-gain fuzz
  • Premium passives and mechanical components

Good value

Working perfectly. Install of stereo equipment and carpet left me wanting some heat and sound resistant materials.

BUY THIS ONE!
Model: NewSLS50_52
This is one of the good ones. There are other brands just as good, and manny brands are worse, but this handles well, rolls down easily, doesn't come off at all easily, and adapts to dips and curves like a champ. Appropriately heavy and dead, I'm happy with the way it smothers panel resonances and even at muffling direct sound, like a big hand over my Uncle Harry's eternally noisy mouth. You can rip the foil but you have to work hard at doing that. Remember to buy a brayer; you can roll overlaps nice and thin. Also remember to pre-wipe the sheet metal with a decent solvent like acetone or Stoddard/Varsol. It should last forever.

Good stuff, but watch the temp
Model: NewSLS50_52
I used this in my single cab pickup truck (89 ford.) It only took half the box (10 sheets or 25 square feet) to do the floors, but I bought the big box because I plan to do the doors, back wall, and maybe the roof as well. One thing I learned is that the temperature matters when you’re doing the installation. It was around 55F when I started in the evening, and when it dipped down into the 40s the sheets would not stick to the metal, and were hard to compress with the roller. That’s why I ended up only doing the floors and not any vertical surfaces; i will have to wait for a nice hot day. The other thing is that the foil layer on top is razor sharp at the edges, definitely wear gloves! I didn’t notice until after but I have little papercuts all over my fingers. Aside from those things, the install was easy and straightforward. The sheets cut easily with scissors, and any goo that ends up on your hands or scissors can be cleaned up with acetone (nail polish remover), or lacquer thinner. I would use this stuff again.

Great option for a great price
Size: 7.5, Color: Black
I love these sandals. They are well made, true to size and soft suede. They are lightweight and feel just like my UGG goldenstar sandals. (These are not as adjustable, so if you have narrow or wide feet, these may not be for you) These a great value for the money, especially for medium width feet. The strap across the toe is not adjustable, but fit my feet just fine. The ankle strap was a good length for me. And the Velcro is strong. These sandals are a great value for the money. I will probably start looking into kookaburra before I rush to buy the more expensive ones now.
