What I had on that guitar before was a cut off Tele bridge, but a fat flat plate one. And it used to have a Super Distortion pickup too. So it wasn't a straightforward bridge swap. Those are Duncan '59s in there now.
I'd say it's more Tele'ish having the pickup mounted in the bridge, but not in a Twang sort of way. But any time I want to play a Tele while the TV's on, this one's a good choice. This guitar has lots of sustain too, and it's always on the edge of feeding back. But no real single coil sound. It's a ham fisted Tele without much subtlety.
It's been too many years since I've heard it with it's original ashtray bridge. I almost feel bad about hogging it out for humbuckers, but I've gotten a lot of use from it since I started modding it.
