well.....maybe you'd like to specify what kinda problem are you having with vibrato and bending?
for vibrato, you can use either one of 3 fingers to rock the string. pick a note anywhere, and just create an up-and-down motion. its easy
G|---7~~~-----------------
for bending, there are many different types of it. double bends, quarter note bends, full note bends, unison bends yadayadayada..technique wise, you just wanna keep in mind that you're bending a note so that it sounds like the note you wanna get.
G|-------5-5b7-5-------------------------------
D|---5-7----------7~~~------------------------
if you listen carefully that 5b note is equivalent to the E note on the 9th fret G string. using bending can be a great advantage to your playing as you can sometimes play "hard to reach" areas lol.
in addition, bends and vibratos make a great team together too..
E-----10-------------------------------------------
B-13b----13---10---13~~--------------------------
G------------------------12b-12-10----------------
D--------------------------------------10-11-12~~
A-----------------------------------12-------------
i hoped this worked.
cheers
