Can ne1 tell me what is L key and what's the function of L key. Coz I've acoustic guitar with L key option but I dont know how to use that, But I know that there is a little point for that key inside the Sound Hole, but I'm affraid to use it... Plz answer my question... Thanx
are u talking abt the spanner kinda thing? that might be the spanner to adjust ur truss rod. in any case, if u don't know what u r doing don't tinker with it.
Are you referring to an allen key? Those are normally used on electric guitars to adjust bridge height.
the neck of a guitar must have a little concave curvature, with the nut slightly higher than the bridge end. This is achieved by increasing/decreasing the tension using a truss rod (if it is too curved then the truss rod must be loosened).

Just a word of caution: You can cause permanent and irreversible damage to your guitar if you tighten the truss rod too much causing the neck to bend out of shape. DO NOT MESS WITH IT IF YOU HAVE NO IDEA WHAT YOU ARE DOING. Take it to a trained professional.
Oh really???? No I will not even touch that damn Rod... Thanx that u warned me before I do that stupid thing.
