Wanted to know if any of you use them. if so, how would you describe how they have benefited your tone? I know in general what they do and was talking to someone about them. I had asked what kind of an affect they had on pinch harmonics thinking that I would be told that they have a negative affect on them, rather, i was told that a compression pedal will make them louder. I found that to be interesting considering how a compression pedal is supposed to work.
