It's my first tab so be nice. It's the blues scale in A and it sounds great. You can make loads of improvisations from it (Try bending on the 7th fret of the 3rd string when playing it backwards, sounds great).

E |------------------------5-8-|8-5-------------------------
B |--------------------5-8-----|----8-5---------------------
G |--------------5-7-8---------|--------8-7-5---------------
D |----------5-7---------------|--------------7-5-----------
A |----5-6-7-------------------|------------------7-6-5-----
E |5-8-------------------------|------------------------7-5-
