Although I'm very happy with my backup Mexican Strat the only thing I find difficult is the trem bar doesn't have as much room to move my hand as the American Strat and I noticed a few differences in the bridges and trem bars today as in the attached images.
I'll be getting the guitars serviced/set up where necessary by experts as I'm too scared to touch them myself at this stage but wondered if all the Mexican Strat needs is the same tremolo bar as the American Strat to make it more comfortable or if the differences in the bridges mean they need different tremolo bars. I haven't tried it yet. I suppose that's the obvious thing to do
Best wishes
