Hey man, ive got a problem,
when ever im hammering on in situations like this:

|----7p5--
|---------7

like that over and over really fast, on the last 7 whenever i take my finger off, it rings the string as an open, when clutters up my solos and stuff

also when i bend, when i reach the top and coming back down, it makes an open sound of the string about it,
this is obviously bad technique, all my technique needs work anyway i suppose. But how do i fix it, any suggestion,
Muchos Gracias
