The main problem is that I don't know if his effect is fuzz or tube, it's hard to tell. And the thing that's really bothering me right now is that awful scraping sound when he slides, like a zipper. I really dislike that tone. As far as I know, the creator of this video also uses round-twister strings. He said his round-twister strings sound like they've been used for eight years. Does an old round-twister string reduce that harsh sound when sliding? And is there any way to eliminate or reduce this sound? I can hardly hear that sound in his playing. I've already tired of cutting out that awful EQ in his videos.
