Hey guys,

I'm not too good with guitar hardware jargon, but I have a Squier Strat with 3 springs behind the guitar which is for doing vibratos with the whammy bar. My friend also has a Squier Strat Bullet but with 2 springs, but he can also tighten the strings abit by pulling the whammy bar the other way. I also see people selling strats with 2 springs. Is there any major difference?
