Bridge is wound a little hotter. If you want a hotter middle pu, you could use a bridge just fine. But I would recommend staying with the neck/middle model if you crave killer quack.
Thanks. Not sure how much quack I'm looking for. I just won an ebay auction and thought I was bidding on a middle but it wound up being a bridge. :-(
I have a JB TB4 in the bridge and was going to place a 59er in the neck.
