I got a guitar with whammy, not a floyd, is there such a thing to hold it in one place like a fixed bridge so that I can't use it so that strings don't detune.
i had the same prob. I just undid the back cover then put cardboard between the body and the block that u put ur strings through. Bit budget but, whatever.
^ A chunk of wood would be better than cardboard.

No, just shove a wood block in there and call it a day. I have a piece of oak in my guitar. That shit's hard as hell.
Yeah a piece of wood is the cheapest and actually really efficient way of doing it. It won't ruin anything. It'll be fine.

Also, cheers. I have a friend in Rakvere, Estonia.
