neck problem

Are you sure you're not muting the open string accidentally with one of the fingers involved in the bend?

You play lying down? And the guitar responds differently from when you play standing or sitting?

I often find that when I bend one string all the others respond.

must be normal. if you think about it. by bending a string one is altering the string tension on the guitar, bridge, neck, etc. so I would think that all the other strings would respond.

my strat plus does that. I call it my rubbery guitar. I like that aspect. I can pull on the neck headstock and alter pitch. press on the bridge and alter things.

my 2 cents.

Dogbite: I'd expect it on a guitar with a whammy, but not on anything else (obviously the effect would be taking place, but I wouldn't expect it on a scale that I'd notice). It's the whole reason I chock up my whammy - I hate it that much I live without divebombs and gargling :)

Jason: Is it on a guitar with a chocked up whammy rather than a 'real' fixed bridge? Maybe the chock needs a once-over? Mine wooden one used to work itself loose every now and then, so I use a pile of pennies glued together now - I'm not proud :)

i'm not muting it, it just goes flat about a quarter step.
and, no. there no whammy bar on it at all. it's a set bridge designed so that the strings go over the backstop.

Jason,
Putting pressure on the neck loosens tension on the strings. So if you play a chord, then put pressure on the top of the body of the guitar with your forearm, and give some pressure to the back of the neck with your fretting hand, you can get almost a tremelo effect. DISCLAIMER: Don't put so much pressure on the neck that you snap it. Nobody likes to have a broken neck.
