Option A....
I route a small pocket on the rear of the body so the tuner is recessed in the rear and won't be knocked out of adjustment during normal playing. The strings would feed through ferrules in the headstock from the rear. The ferrules would be partially hidden under the lower octave strings for aesthetic reasons. Working out the exact route design that offers enough room for comfortable tuning without interfering with bridge or strap mounting hardware is the next step. I'd probably just finish the routed area in semi-gloss black which should look fine since it's recessed......and on the back of the body.
Option B....
Would be a more traditional 8 tuners on the headstock configuration. It would be great if the spacing could be even but it isn't possible without a refinish and possibly headstock lengthening surgery. About the only option that works due to the way the strings feed on the high octave tuner is to offset them.....no string interference this way. The actual tuners would look better than the tuner nuts that I used for layout purposes but I'm not sold on the aesthetics as it is. I may be able to tweak them for a little more balanced look but this is pretty close. I'd still have to actually make a headstock with an 8 string nut to make sure of the clearances before moving forward.....but with the way it looks I don't think I'll bother.
Option C....
Leave it alone and do nothing......nothing is what I do best BTW!
Considering the options I'll probably leave it alone but if I decide to do anything I'm convinced that the octave tuners mounted at the tail is the way to go. Better balance as a bonus......compared to 8 tuners on the headstock. The next step is to pick up some scrap wood and work out the routing. The ultimate goal would be to use ferrules at the tail as well and keep the octave tuners completely concealed but I'm not sure if the body thickness and hardware would allow this along with maintaining structural integrity. I should have this done or a decision at least by 2013 considerinhg my current pace.
