Re wiring a "harp is a dangerous mission. I have several that have the strings they came with still on them and I think they sound the best. Here is a very audacious move for some with more than one harp.

Double tune it. By that I mean decide what single key you want it to play in, "C" works best but others are Ok too. Tune all the sharps to naturals, this puts two "C" strings next to each other, as well as "F", "G", "D", etc. Now you will have to open the bar blocks and widen the felt gaps that allow the strings to vibrate creating a chord. NOTE: This can't be done for all the chords, like the "D" major and the minors some chords require sharps (or flats) so plan your changes against the chords as needed.

Down side, you lose 7ths but with some practice you can pick the 7th notes out of their constituent chords. Like grabbing the "E" for a "G7" out of a "C" chord forinstance.

My Double tuned Harp is an old Appallachian 15 bar changed in this manner. Major course is set up "F","C","G","D". The minor course runs "Dm", "Am", "Em", "Bm".

This rig is great for solo performing in no more than two keys. You gain powerful sound. I wouldn't ever suggest doing this to a collectors instrument or to your only harp. But if you are like me and own more than 3 Harps, give it a try.
