We have the 57 Hot Rod in our labs for review right now -- that review will be published in our August update. My initial reaction from playing with it and listening to it (though I'm not doing the actual review -- our guitar editor Derek is):
It sounds very un-stratlike in the bridge position
. The DiMarzio ToneZone gives it balls where a strat usually doesn't have them, but it's still not as heavy as a solid mahogony-bodied Les Paul or Ibanez RG with a full-sized ToneZone in the bridge. It lets my Road King II sound like a heavy dual rectifier, though, where standard strats are just too, um... strat-like (which is great for strat lovers, of course).
The strat that I recently fell in love with (as much as you'll find me loving a strat, anyway) was the Jeff Beck strat that we reviewed last month (see http://www.musicplayers.com/reviews/guitars/2007/0707_Fender_JBstrat.php ).
Its pickups are QUIET (ceramic noiseless) but the custom shop winds them hotter than the stock ceramics. It lets your amp break up more easily than a standard Strat, but isn't as hot as the pickups in the Eric Johnson strat. Those EJ pickups are VERY hot, but definitely not noiseless
. I also prefer that the Jeff Beck strat has shaller locking tuners and the modern syncronized tremolo like on Deluxe strat models, and it uses standard five-way switching instead of the more elaborate S-1 switching system.
The other thing I disliked about the 57 Hotrod is that being based on that model, it has string trees and vintage tuners, which aren't that good for tremolo-happy players. We'll see what Derek has to say about it shortly.
