Description:  

Hello, and welcome to the world of the Instant Lo-Fi Junky. Any of you who’ve heard the sound of the Lo-Fi Loop Junky will understand this pedal immediately... its purpose is to imitate that sound in real time. Joel Korte, the extraordinary engineer behind this new device, was able to create a combination of THAT chip compression, Belling bucket- brigades, and ultra low-current National Semiconductor op-amp filters to exquisitely copy the texture and feel of the original Lo-Fi into this new and extraordinary box, adding some new sounds that have never been heard before.

To get the basic real-time Lo-Fi sound, turn the middle knob all the way to the right and set the waveform switch to triangle. By adjusting the speed and depth it’s pretty easy to achieve a very similar texture to the original Lo-Fi Loop Junky. Lower the tone knob if you wish to darken the tone.

Next, try turning down the middle knob all the way toward the “comp” side. With this setting you’ll enjoy a remark-
ably spanky bright and clear compression. It lasts forever but has dynamics like there’s no tomorrow. As you turn
the middle knob back toward the Lo-Fi side, you’ll hear the chorus blend start to happen. The sparkly clear compressed signal will mix with the smashed, lo-fidelity warbled signal and become a luscious emulsification that can be blended to the most perfect depth. Unlike other choruses where

the only depth control you have is the depth of the sweep oscillator, this unit lets you set exactly how much of the two signals are present in the mix... more clear compression
if you want the sound to be basically clean with a hint of chorus, blended 1-to-1 for pure chorusing sound, or mostly vibrato with a hint of chorus by turning the knob mostly to the right. The chorus sound sounds most traditional with either the sine or triangle setting. They are subtly but notice- ably different.

Now try switching the waveform to square and set the middle knob mostly to the compression side (to the left). You can blend in just enough of the square-wave modulated Lo-Fi sound to make it really eerie. For the spookiest sound, set the speed control to the tempo of your performance and the depth all the way up, adjusting the mix for just enough modu- lation. I really love this setting... it’s so unusual and fun.

We had a producer come through our booth at the NAMM show when we were demonstrating the Instant Lo-Fi in 2011, and we turned it off to show how much sustain the compressor had when it was engaged. He looked at Erik (our demonstrator) quizzically and said “but why would I ever

want to turn it off?” Maybe you’ll feel the same way about the Instant Lo-Fi. It’s dangerously addictive.
OPERATION
Plug your guitar into the input jack and your amp into the output jack (or you might mix it with other pedals). It can be anywhere in the chain, providing different textures depend- ing on it’s position in the lineup.

THE CONTROLS

Volume: Overall output volume for the unit.

Tone: Can be used to lower the brightness of the Lo-Fi signal (the vibrato sound). Does not affect the compressed signal.

Comp/Lo-Fi: Adjusts anywhere between full compression and full vibrato mix. Blending the two (somewhere between the

extremes) creates a chorusing sound.

Speed: Adjusts the speed of the Vibrato (only affects the Lo-Fi sound).

Depth: Sets the depth of the Vibrato (only affects the Lo-Fi sound).

Waveform: Sets the waveform of the Vibrato’s modulation. The traditional Lo-Fi Loop Junky simulation setting is triangle.

BATTERY CHANGE & POWER SUPPLY

The Instant Lo-Fi draws less than 20mA and can be pow- ered with a 9V battery (remove the four screws on the bottom for replacement) or any standard filtered/regulated musical 9VDC power supply with a Boss-style connector (negative-tip barrel connector). We recommend using an alkaline 9V battery but a carbon-zinc battery (shipped with the unit) will work.

WARRANTY

Your Instant Lo-Fi JunkyTM is warranted for 1 year from date of purchase, or 2 years if you send in your warranty card.

    Warm, Comfy, and No Electricity Needed
    Size: 20.0"L x 16.0"W x 0.5"Th, Color: Grey
    This self-warming cat mat works well — it reflects body heat and stays noticeably warm without plugs or electricity. The surface is soft and cozy, and most cats seem to take to it quickly. It's lightweight, easy to clean, and fits well in beds, carriers, or on furniture. It’s a bit thin, so adding extra padding underneath may help. Also, it can slide on hard floors, so best used on carpet or fabric surfaces.

    It's a hit!

    He loves it. I wish I had purchased the large instead of the medium, but it still fits him okay. If he stretches out, it won't, though. :) He's a big boy. I have it lying on a bed in the spare room, where he often is, looking out the window. It's soft and makes barely any noise. It doesn't slip on the bed. I might on the floor. With anything new that we buy him, we spray it lightly with catnip spray and he always takes right to it, as he did with this. It's warm under his body. He's happy, we're happy! :) I ordered the larger one. It got here today! I moved the smaller one to a window seat. I hate when the delivery guys add, was handed directly to homeowner, no it wasn't It was put in a package box outside, ringing the door bell is not the same as handing it directly to me! LOL

    My cats love their self heating mat!
    Size: 27.6"L x 18.8"W x 0.5"Th, Color: Coffee
    I use this as a cover on my loveseat. It took my cats a few days to realize how much they liked their new mat. It makes a little crinkle sound when they walk on it but they don't seem to be bothered by it at all.

    Thinner Than Expected but Still Gets Used ULIGOTA Self-Warming Cat Mat
    Size: 20.0"L x 16.0"W x 0.5"Th, Color: Grey, Size: 20.0"L x 16.0"W x 0.5"Th, Color: Grey
    This self-warming mat is much thinner than expected, and the corners don’t lay completely flat—they tend to curl upward, which makes it look a little cheap when first placed down. The material is soft, though, and despite its lightweight feel, it does warm up slightly when the cat lays on it. It’s not plush or padded like some other warming mats, but it still provides a cozy surface. Pros: • Soft surface • Lightweight and easy to move • Cat actually uses it • Self-warming layer works to a small degree Cons: • Much thinner than expected • Corners curl up and won’t stay flat • Doesn’t feel premium Verdict: Even though it’s flimsier than anticipated, my cat sleeps on it consistently—so it’s staying. For pets that don’t need much cushion, it’s a decent budget option, but buyers should expect a very thin mat rather than a plush warming pad.

    Works just as intended

    My recently adopted rescue kitty loves this self-warming mat. We live in the south, and sometimes the temps drop a bit. I placed her mat out onto some blankets and she was immediately receptive to it. I sat and gave her plenty of cuddles while she laid down on the pad, and I could feel the toasty warmth beneath her body on the fabric. The size of the mat you see in my photos is the 16”x20” size. My kitten is 6 months old and she is a gangly, lanky girl. She fits on the mat when curled up- but she likes to sprawl as well. This size is great for inside her travel carrier, but I will more than likely also order a larger size for home use so that I can keep the smaller one in her travel carrier. I ordered the brown and I like the rich, chocolatey color. The top is a very fine micro velvet that is very soft. The underside is polyester that has some small rubber dots for traction. It is thin and very pliable. The mat is great quality and has held up with my kitty attacking it during playtime as well. Whether for home or for travel uses- it’s a big hit with my kitty! Works just as described and makes a wonderful addition for these colder months.
