I bought one of these a couple of weeks ago and can't believe the difference it makes. I would really like to see what settings others use to get various tones like Slash, Van Halen, Hendrix, Trower, Stevie Ray Vaughan, Guns and Roses, etc.....I'm not sure it sounds better in my effects loop or in front of the amp. A lot of experimenting lies ahead. On another note, I can't get my strat to give me that liquid rich tone of Slash's first lead riff in Paradise City. Perhaps the strat can't make the Les Paul neck or neck/bridge mix "woman tone". Maybe it's something else? Thanking you in advance.
