Strats are THE mod guitar! Just unsolder the current pickguard and drop in a new one with new electronics. If and when you sell, you can return it to stock in 5 minutes, plus you keep the new (and probably more preferable) pickups. Shoot, swap necks, bridges, anything... They are so awesomely modular no one will have an idea you did anything...
I'm curious about whether or not I should mod Fender American stuff? Will it devalue to the guitar?
I'm not talking about cutting in a new pickup or swapping out necks or cutting my name into the body of the guitar. I'm just talking about doing a simple pickup swap, maybe change the pickguard, change out some of the electronics?
If I were to perform those sorts of things, would it be fair to sell the guitar for used Fender American prices, still?
Go nuts with it and post some pics!
