Hello @Troy,
I was very (very) interested in your project on building the right sized guitar for little handed players (let’s say not that tall persons) but I do remember that you didn’t posted any further video since the first one, maybe 3 years ago now ?
I am 1,72m sized. Not the smallest man alive, but still I feel a bit small handed for a majority of guitars, particularly my given-for-birthday Jackson King guitar … I am seriously considering the question, and build my guitar on the right size (especially for the neck).
I think i’m not the only one being enthusiastic to know what’s next. Please give us some spoil if you have. 

Even before fixing noise issues and replacing pickups, the bridge pickup and pots are not the original ones, and the toggle switch has been added, is it from you or you bought it with these mods ?
