Hammond Leslie 991 Bi-amplified Keyboard Speaker CabinetFrom the inimitable whirl of a Hammond organ to John Lennons infamous, swirlicious vocal overdub on Tomorrow Never Knows, the inimitable Leslie keyboard amplifier has produced some of the most iconic sounds in music history.

Each powerful 300 watt bi amped unit incorporates the rotating 15 inch woofer and high compression horn

From the inimitable whirl of a Hammond organ to John Lennon’s infamous, swirlicious vocal overdub on “Tomorrow Never Knows,” the inimitable Leslie keyboard amplifier has produced some of the most iconic sounds in music history. Now, the Leslie Models 3500, 3500W, and 991 bring you that soulful sound with enhanced high-definition clarity and presence. Each powerful 300-watt bi-amped unit incorporates the rotating 15-inch woofer and high-compression horn driver from the vintage reproduction 122H and 142H heritage models, which have been huge hits. At Abbey Road Studios in the ’60s, the engineers had to jailbreak the input circuitry in order to amplify guitars, vocals, and other sources through a Leslie. In addition to the customary 11-pin jack that directly hooks up to your Hammond organ, the Model 3500 is spec’d with a standard 1/4-inch line-level input, conveniently allowing any instrument to be plugged straight in.

Modern features, epic sound
Working with a vintage Leslie offers sonic rewards, but compatibility and reliability can often be challenging, as is the case with all vintage gear. In contrast, the Leslie Models 3500, 3500W, and 991 give you all the sonic benefits of the cherished originals, plus high power, enhanced clarity and presence, and functional modernization. This cab’s brushless DC servo motors are not impacted by power frequency or voltage fluctuations, and it’s highly resistant to unwanted RF problems. Plus, you can even adjust the rise, fall, and rotor speeds to your taste. The new models are also equipped with a new solid-state preamplifier that reproduces the characteristic overdrive distortion of transistors. When presented with a gentle input level, they serve up lush, velvety warmth. Hit them hard, however, and they positively wail with a full-on classic rock scream. You can control these coveted overdrive characteristics with the Overdrive on/off switch and the Gain knob on the bottom control panel.

The definitive evolution
The Leslie Models 3500, 3500W, and 991 differ only in their cabinet specifications. The road-ready 3500 is built into a tour-tough chassis with ergonomic handles and heavy-duty casters; the 3500W rocks a classic walnut cabinet that lends a touch of elegance to recording studios and houses of worship. On the outside, the Model 991 is the quintessential vintage Leslie with a full-sized, furniture-grade walnut cabinet. Under the hood, however, all three of these state-of-the-art high-powered keyboard amps represent the definitive evolution of over a half-century of market-segment dominance. Without the constraint of traditional wooden cabinetry, the Model 3500 is optimized to efficiently propagate its internal sounds outside the cabinet with optimal resonance and modulation. The traditionally styled 3500W and 991 cabinets feature widened louvers to achieve the same sound-distribution performance. With their state-of-the-art high-power amplification systems, traditional driver configuration, flexible I/O, and acoustically optimized cabinets, the Leslie Models 3500, 3500W, and 991 are poised to dominate the music industry for at least the next half-century.

Ok, but don’t use hand cream
Color: Black, Color: Black
I like the case for its ability to house the keyboard, the pencil and the iPad in one convenient place. I find that the magnetic closure and magnets holding the keyboard are not as strong as a previous case I had purchased. The keyboard is great, I like the touchpad and the backlight colors. The cover material is not hand lotion friendly! I’ve tried water and lens cleaning wipes, and neither gets this cover clean. I hesitate to use any chemicals because the material is the type that will get sticky and nasty, and I don’t like that. I’ve included a photo of what the cover looks like after using a lens cleaning wipe. If the magnets were stronger and the cover material easier to clean, I would buy again.

great case!
Color: Navy Blue
pros; the color is beautiful. I picked the navy blue. It is exactly as the description described. It goes very well with my blue iPad. The size is very precise and fits perfectly on my iPad. The magnet that holds the case together is very strong. The iPad itself can pivot vertically and horizontally using that magnet. This works very smooth. The magnet closure for the case itself is strong and holds well. The magnet that holds the keyboard in place also works very well. Cons; when the keyboard is in its correct position, it is difficult to angle the iPad in front into the provided grooves. The keyboard gets into the way. This prevents the iPad from reaching the grooves provided. The keyboard feels very light and cheap. The keyboard itself connected with the Bluetooth very easily. It works wonderful. I love the back light on the keyboard. The color of the keyboard is wonderful. However, as I said above, it does feel a bit cheap. But for 20 bucks, what can you ask for. When the case is folded together with the keyboard in the iPad, it is a bit bulky. But I knew that from the previous reviews and was expecting it. What I love most about this case is that the iPad can be removed using the magnet on the back from the keyboard portion, but it is still protected by the exterior plastic case. So in situations where I don’t need to use my keyboard, I can remove the iPad itself and know that it’s still protected overall I recommend this product.

Nice Case & Keyboard
Color: Blue
Love this case with a keyboard. I like using the keyboard vs using one on the screen of iPad. And the keyboard has rechargeable batteries instead of having to buy batteries. And it protects my iPad.

Beautiful, and everything I want it except that the keyboard keys didn’t work😭
Color: Light Pink
I searched and search for the right keyboard case for me. The most important thing for me was to be able to remove the iPad case itself from the whole case and keyboard, and this one was it. Unfortunately, when I started checking the keyboard a lot of The keys were not output in the correct symbol or letters. So defeats the whole purpose of having a keyboard. I returned it and asked for a replacement, thinking that the item was defected, but when I got the New replacement, it was the same thing so I tried to contact the seller, but there was no option to do that. Therefore, I had to return the second replacement keyboard and look for another keyboard cover.

Great quality at a remarkable price
Color: Navy Blue
I got an iPad and was looking for a cover to protect it. I came across this case that has a Bluetooth keyboard. It seems to be working great. It was less than $30 and had 4.5 stars with over 4k reviews. The keyboard is magnetic and detachable, so I’ve got lots of configuration options. The keyboard pairs easily and allows you to use the iPad like a laptop. The point of an iPad a lot in one shot is kind of the touchscreen, but when I’m typing a lot of text as once (like now), it’s really nice to have a physical keyboard and touchpad. The keys are comfortably spaced and I’m comfortable typing on it. There is no additional setup for the keyboard besides pairing it to the iPad. At that point, all the cursor and keyboard features are immediately available. The case is well built and has nice features like a slot to hold a stylus and multiple grooves to set your viewing angle. It’s configured to be used in landscape mode, but if for some reason you wanted to use it in portrait mode, you can pop the keyboard off to lay it flat. Especially for the price, this is an exceptionally nice iPad cover.
