I just got my Lanikai LU-8 8 string. All my experiments in tuning have lead me to being happy with as I call it " double-island " tuning. Keeping the string and the sympathetic ( for lack of better word and/or technical term )string at the same octave. When you leave the bass string ( at the top like an acoustic guitar ) open it leaves a nice loud buzzing and hum to compliment the higher chord sounds. I have two instrumentals that I have recently put together, when I get a little more confident in my playing I will upload them. 8 strings might be intimidating, but I am glad I took the leap into them. Anybody else gone 8 string yet?
