Thanks for all the suggestions. i do use tissue for the high e and b strings if they're not going to be played, but i can't foam the low strings, since i realase to an open drop b tuning. The problem isn't that any strings ring out in the silent measure, it's the actual final palm mute - the noise made when my hand deadens (puts the brakes on) the last chord of the measure - with the low tuning and the high gain, the actual pushing down on the strings is "heard" by the pick-up as a low frequancy, quick bark. This low freq cannot be suppresed with a noise gate. Gotta go with Jeff, get carpal tunnel, and edit the end of "the blobs"
BTW, I'm not too concerned live - with all the ambient noise on stage, no one will hear it, or care.
