This is something that's been bothering me for a few weeks now and prompted by this post from XRB

I'm just starting out on bending strings (I'm learning Wonderful Tonight) and everytime I bend the strings, I catch the strings above the one I'm bending i.e. my fingers go under the strings above the one I'm bending so that the (non-bent) strings are above my fingerips.... sometimes catching my nails (which are very, very short) leading me to believe that the overall action may be too high.
I'm thinking I need to lower the action a little so that those non-bent string go under my fingertips...everytime I've seen someone bend strings, this is what I see happening. Looking at online forums (quotes are from another thread responding to someone who had a similar query), there's plenty of disagreements....so which one works for you?
whenever i bend on guitars with low action, my fingers always catch the string above the one i'm bending, so i end up playing a SRVish 2 string bend instead of just one.
Sounds like maybe too much finger "pad" in contact with the string, as opposed to fingertip.
If you're laying your fingers too flat, when you push across the fret to do that bend you're just gonna scoop up the next string right along with one you're hitting. If you can get a little more arc happening in the fretting hand fingers so the tip is coming down clean on the string with good pressure, you'll be more likely to just push the next string out of the way as you bend.
Maybe raise the action a tiny, tiny bit and get up on the fingertips a little more often. Either way, it's not rocket science, if you work at it you'll figure it out eventually whatever set-up or technique you use.
Everybody does it a little different.
This is a personal technique or physical problem of the user, not the guitar.
Even with action so low that the strings are almost laying on the fretboard there should be no sound coming from adjacent strings that are coincidentally bent.
Out of curiousity - you are always going to grab more than one string when you bend, you have to.
But it sounds like you are saying you are hitting more than one string with your picking hand, otherwise you wouldn't be hearing more than one string.
I have personally picked up a style where I mostly up-pick (right or wrong). I can tell you that one advantage is in bending strings - you usually hit just the right one.
This may not work for you, but your problem is not one I have. If I want to play a two string (SRV-style) bend I have to work really hard to get it.
