Revolutionizing Ukulele Sound: Lava Music Lava U FreeBoost Review & Demo | Ashkan Roohi Special 

I own one and while I like it, I had to mod it so I could attach the straps I wanted (glued on a strap knob from another company) and the case is too small to fit a strap. The panel in the case barely fits a tuner and my pick case. Their proprietary straps are A: Sold Out and B: Not to my taste. The effects can be difficult to hear unless turned all the way up. Not much going on in the mid range. But of course sound good up high, unless it starts ringing.

What size is this?

What is the name of the song he is playing?
