NOOB here wanting the Cliff Notes version of what a TubeScreamer does and why that's a good effect to have. I GOOGLED the Ibanez TS line, found 5 different models and would like to know how do I figure which if any would be right for me in the future. Could one of you explain the differences to me? I play blues and slide if that helps. I saw a YouTube clip of a guy playing an acoustic w/pickup that he ran through a TS and I was blown away by the sound.
