Yamaha E Series Keyboard

[10 x 3.5"] Covers my yamaha np-30 keyboard perfectly.

[N/A] Perfect inexpensive coverup for your Yamaha or other same sized keyboard.

[61 Keys] This Yamaha Keyboard Bag is just great. It's compact. It's a perfect size for my keyboard to fit in. It protects it on all sides.

[3.03 lb] Very well made - correct piece form my Yamaha EW425 keyboard.

[USB-A] Got this cover and it fits really well on my Yamaha-45 [ 88 note keyboard ]

[5.0] These work perfectly to house the Yamaha STAGEPAS 600i (or 600BT) series PA speakers. Note: it is one case, so you'll need to snag two to cover each speaker. The rolling function is fantastic, and the case itself packs down quite nicely.

[-100 dBu] I use this on a Roland and Yamaha digital keyboard. It really smooths out the response of the keyboard and helps tame the harshness.

[Active] Bought this to compliment my Yamaha DGX-650 keyboard, and it works exactly as designed. Plugged it in to my keyboard headphone jack and adjusted the volume - viola ! I will someday upgrade to a larger unit when performing, but for now this meets my needs perfectly for practice - not too large, not too small, just enough power to fill a large room with legendary Yamaha sound. I may even add another one just because.... A bit pricey, but you get what you pay for. This unit rocks !

[Empty] I use the case for Yamaha S-910. I have to add some padding on one side to make it fit, but the keyboard is well protected. Best imaginable case for the price.

[Yes] While the Yamaha keys do feel more like grand piano keys, this keyboard SOUNDS better than the Yamaha 143. recommended.
