I recently bought a Fender Stratocaster, and have noticed a problem that im not sure if it is normal or not. I bought a strat that included the whammy bar, so the bridge is held down by springs. The problem is, is that i notice the bridge rises whenever i tune my guitar, meaning the tighter my strings get the more of an angle my bridge gets. Also when i have to replace strings or want to try differerent tuning, the harder it is to stay in tune because the bridge is always moving. Im not sure if this is normal for guitars that have whammy bars, or if this a problem i can fix. Please i need to know.
