Hi,
Are you playing acoustic or electric. I personally think the overtones and harmonics on an acoustic
slide provide some very pleasing sounds - greasy as one of my friends calls it. On electric, I tend to like the cleaner tones and use a combination of palm muting and behind the slide damping. But I do let up on this for some tone variation at times.
I am glad we are getting some more action on the forum as well.
