Awful Waffle sounds fizzy

Finally got this build to work, but I notice that turning the gain up past 9’oclock creates an undesirable fizzy spitting sound. Also the volume is crazy sensitive and very very loud. Is that normal?
 
What op amp did you go with? I found the op amp used can make a bit of a difference. I think I settled on AD711 for mine, but I just happened to have one. I think the TL071 was smoother than the UA741 I had if I remember correctly.
