I don't know why I am having such trouble with this, but for some reason I can't keep the chord ringing out when I slide from the low b chord (2nd fret) to the high b chord (14th fret) in the beginning of Comfortably Numb. The chord dies out by the time I get to the 14th fret.

I have tried using a compressor pedal but it doesn't make that much of a difference. I am pushing fairly hard against the strings to try to make sure I don't mute them accidentally.

I'm not sure what I can do here.

go slowly at the beginning of the slide, then when you get closer, speed it up so it works almost like a hammer-on. a little vibrato helps sustain too
