Re: Edge pro tuning help!
If you wanted a guitar that could be drop tuned, you might have purchased the wrong one. Anyway, relax. Here's what you should do. If you have a complete spare set of strings, put them on the guitar. Remove all the old strings you've used up all at once. I repeat, all at once. Put these on the guitar, stretch them a bit (pull on them with fairly strong force, but not enough as to break them) near the 12th fret so tuning is easier. Set the fine tuners to the middle of their tuning range. Now, starting from the thickest string, tune it up to E. then move on to the other string, tune it up to A, and so on and so forth. (you'll need an electronic tuner for this).
If the strings touch the frets and aren't making a discernible sound by this stage, just tune up each string evenly until the bridge raises, and the string pitches could be detected by the tuner. Again, start at the thickest string, tune it up to pitch, then the next, and so on and so forth. After tuning the high e, go back to the thickest one and you will find that it is no longer in tune. Just continue tuning the strings from the thickest to the thinnest and you will notice that each time you go back to the thicker strings, they go out of tune less and less until it reaches the point where all strings are in tune.
However, while doing all of this, you must check the angle of your bridge. it should be parallel to the body of your guitar. If the bridge pulls forward a bit too much, you must tighten the two screws holding the spring claw at the back of your instrument. If it's too low, loosen them. Turn them in increments of quarter turns (trust me, a little turning goes a long way) and make sure you turn both screws evenly. Usually stock strings are a bit thicker than the gauge 9 strings one could buy from music stores, so the screw turning is often needed.
After a couple of screw turns and tunings, you will be able to tune your guitar. However, it won't be the end of it yet. Carefully lock the pressure pads near the headstock, and recheck tuning. Adjust on the fine tuners as necessary. Try divebombing and pulling up on the tremolo bar a couple of times and see if it goes out of tune. If it does, unlock the nut, retune, then repeat. If not, put it in the case and wait until tomorrow.
When the next day comes, recheck the tuning of the guitar. This is usually the time it takes to allow the truss rod in the neck to resettle. If it went out of tune, just retune it and you're done. If it didn't, then congratulations.
Hope this effing long article could at least give you an idea of what to do.
