Korg Opsix six-operator FM synthesizerThe Korg opsix represents a new and expansive reimagination of classic digital synthesis. Much like Korg did when bringing wave sequencing back in a more powerful, more musical, and more immediately accessible way with wavestate, so was the approach to FM sound generation on the opsix, resulting in another incredibly flexible and unique synth.

LOVE these visors!
Size: One Size, Color: Navy Blue
I love these visors. They are the best that I have ever purchased. They are so comfortable and stay on your head without slipping and sliding while playing golf. I have three colors, and anticipate I'll be buying more colors soon!

Lightweight and comfy!
Size: One Size, Color: Fluorescent Yellow
Love this visor! Super comfortable and stays in place while running. Not super tight. I am a little worried it might stretch out over time and no longer fit, but as of right now, it is perfect. I ordered it in two more colors!

Too cheap for its price, not expecting it to last long
Size: One Size, Color: Rose Red
Flimsy and cheap feeling, you can find much better visors on Amazon for a few bucks cheaper. The bill is small, shorter than expected and it amuses me that the overly-long product “title” mentions being appropriate for men because I believe this visor would look ridiculously small on a normal man’s head. Honestly, fresh out of the package I wondered if I missed some detail about this being child sized. I do like that it is lightweight and that I won’t have Velcro stuck in my hair, though as an experienced seamstress and crafter I can already tell this is going to lose its elasticity FAST (as other reviewers have mentioned). I do love the color.
