I like so much this product. Fits perfect and solved a lot of carring problems. Now I can walk around with no worries.But I need to say it's a travelling bag with some acessories for the SV1. Without the keyboard it's not hard. In my case I put a thin board under the fabric to reinforced the structure. Maybe a extra protection to the knobs zone should be better.But anyway I retired my old flying case. There's no better soft case for the SV1 . I really recommend it!I would like to add a opinion: I have a bad impression about exterior zippered pockets. I wondering the zippers could be a better material for a almost 200 dollars bag.Great case for the SV-1... keeps it snug... but it's WAY overpriced. The quality isn't what you would expect for the $. Wheels are functional but flimsy and the tiny zippers are ready to break off right out of the package. Am I glad I own it? Yes! Because nothing else fits this keyboard so well. Lots of compartments for gear though. That's nice.If you have an SV1 keyboard, you probably have found out that there are few cases or bags that fit it, unless you get one that is much longer and wider than necessary. This Korg Carrying/Rolling bag is perfect for me. The reason it doesn't get 5 stars is it is rather expensive.The Korg CB-SV1-73 was advertised as being able to carry the SV-1 stand right along with it. It does do this, but the pouch for the stand doesn't quite zip all the way when you get the stand inside.It could use a handle on the bottom so that a second person could help carry the case up and down steps and in and out of venues.But overall, a great case, stripped down so it's not too big. It'd fit in the back seat of a sedan.After my husbands Korg SV-1 plus this carrying back got stolen out of the back of our car (window smashed in and all - thanks people who think they need it and the money more than us!), we bought a second one of these cases. They're quite sturdy and it's so easy to lug around the keyboard in it. You can carry it with the handle, but on even surface you can just drag it along behind you on its rolls. Thumbs up! :)Not a great case but a good case as long as you're gentle in moving it around. Be careful with the zippers. I will probably get a better case in the future but this will work fine for now.The first day I used it, it wasn't stowed as well as it could have been and fell out of my mini van when the door opened. The keyboard wasn't harmed at all. It's sturdy for a soft-shell bag. Love the rollers and pockets. Fits the KORG Stage Vintage 1 perfectly.I purchased this bag, because it is made specifically for the SV-1 88 as well as the Korg folding stand for the SV-1. Unfortunately, the zippers are of a very low quality, especially considering the price of the bag as well as the weight and bulk of that which it is meant to contain. I am currently working with Korg for repair/replacement under the warranty, but I would never buy this bag again.It's a great bag, i love the wheels, but the section for the stand for the SV1 could be designed better. The feet of the stand rub against the lining of the case and it's already wearing through after just 4 gigs..Sehr gute und stabile Verarbeitung. Bei mir wird es Zweckentfremdet.Wird für mein Vorzeltgestänge verwendet. Super zu transportieren und ist sehr stabil.Sehr stabil. Mein E-Piano von KORG (88 Tasten) passt perfekt rein. Innen gut gepolstert, sodass das Piano gut geschützt ist.This bag protects in simpler situations. If you need to move much in the same city without putting your piano with other equipment. The ability to take the stand in the same bag was a brilliant idea. At the same time, the stand provides more support for the piano in the bag. The bag weighs little, but together with piano, stand and bag are very heavy. The delivery was very fast and the bag arrived well packed.Le SV 1
