It's simple technique. Difficult to diagnose when I can't see your fingers. But try to change your fingering technique slightly. You need to press more perpendicular to the string you're bending and keep that position through the bend. This is more of a problem for the electric player than the acoustic player, so you also need to work on your muting. I do this on the fly constantly with my acoustics. Sometimes it's just nearly impossible to keep another string from ringing, so muting it quickly will serve the same purpose.

Thank you for the quick reply. :) I will try to follw your advice and I guess the problem might dissapear when I get better at it. Still a newbie. :)

Sometimes it happens to me, but I always try to find a way of avoiding it. (muting or perpendicular, like Xark said)

I always get sound from the other strings when I bend because I have short fat fingers. I do little slides in the place of the bend simply because it's easier for me and it eliminates that feedback from the other strings.

What I do is kind of arch my fingers better so try that and sometimes if your nails are long that will cause it so try to cut your nails if there to long if there not then try some other things like they said mute I normaly when learning a new song just work on the technique like if there a bend then I work on arching and keeping my nails and everything away from there so just keep working with it but it still happens to me and probably everybody well hope this helps...

Keep Rocking...

Thanks all for the help. I god rid of some (not all) of the problem by lowering the strings, they were a bit too high.
