I use the NS-2, and with all my fuzz & OD, it's quite useful. It's a bit of a tone sucker, not enough to not use, but as I understand any noise suppressor will alter the sound. Will batteries really make pedals noisy? I don't use batteries. Going thru your chain is a good idea, but fuzz & OD are often just noisy, some live with it, some try to suppress it. It's certainly not a necessity, but a very handy piece to have in the tool box.
