Hi guys,

I'm just trying to get a grasp of some of the most important scales I will need to further my ability on the guitar, mostly when doing improv. Currently I really only know the blues scale which limits my playing quite a bit. Are there a group of scales that are the most important?? because everywhere I look there seems to be stacks of different ones but I assume they only vary by a note or two from some significant scale pattern? If anybody could help me out it would be much appreciated : ) cheers
