Re: String bending and floating trems
Yes the Tremol-no look very promising.
Another cheaper alternative, or temporary one, that I was told of at my local shop was to try wrapping a scrunchy around/over the strings of the first fret. Not sure what you call them outside of Austalia, but all I mean by scrunchy is an elasticated hair band!!
Sound odd, well it works, the hair band gently mutes all strings except for those you are fretting. Of course you loose the open strings ringing out fully, though they still sound if though they are being palm muted.
Try it, simple and it works. Though I am still gonna buy a tremol-no as they are relitively cheap, and see what there like.
