i feel like a newb for saying this. I was changing my guitar strings on my Epiphone and i changed them one by one but in one day and i just want to know if anything bad could of happened to my bridge?
You'll get such varied opinions that it really doesn't matter, probably 50% will say don't it will create uneven tension on the neck, and the other 50% will say that doing so is better so as to maintain an even amount of force i.e. 0. I personally have done both and it has led to no adversities in my years.
Just me though.
