So I noticed today that sweeping is a lot easier to do in lower tunnings (C,B, and A)

Anyone else notice this?

Thats because of the looser strings. You'll be doing yourself a disservice if you only practice sweeping in low tunings.
yeah, strings are looser. I personally like it when the string are a little higher, you can sweep over without pulling the string with you and the tone tends to be a little bettter (in my opinion)
Are there any excercises to get sweep picking quicker.. i just dont think my heads fast enough for it yet lol
