Does anyone have this?

And if so, got any tips on usin' it?

I got it for Christmas, but I got no clue how to even make any of my own ****......
i got one of these for christmas, too, and my only tip is to trade it in for something better. It had ****ty sound and buzzed all the time, and it was difficult to switch quickly between presets (ex/ from 2 to 15)
