thats not true at all klaze, all you gotta do is take the top faceplate off and lay it face down on a scanner (that's larger than mine at work

) and scan it in. if you scan at 100% scale and set your resolution to like 200dpi then that is plenty to work from in illustrator.
you can measure for the sides and back/front lip overhang, but the button holes are the most important part the way im doin mine.
i was bored last night so i did up the front from that reference photo in illustrator. im gonna print a test sheet and see how bad the photo is off. it definately isnt 100% straight with no distortion like a scan would be. unfortunately my big scanner at work died a few months ago and all i have is a letter sized scanner at my office right now.
if the holes are pretty on in the one i already did up i will just make adjustments and go from there. but we are workin on music tonight so im not taking it back apart to check them out right now.
hopefully i can get with my boy tomorrow so i can get one done early next week.
