    In many ways, this is the best angle to watch Tommy play from. It shows just how gifted he his and how much he has worked to improve his God-given abilities. First, his hands are HUGE ! He seldom puts his thumb behind the neck to reach a string or execute a chord shape. Secondly, this also means that his hands are very strong, as he doesn't need the thumb's leverage. Third, this shows how very nimble his fingers are, not needing the thumb to give him room to navigate the fretboard. 🤯🤯🤯

    Important to point out that if you turn around your slotted bridge pins, even for the treble strings, the bridge itself should be slotted (see your other video from today). If not, as the string comes to tension, the wraps securing the ball to the string are going to chew up your bridge plate.

    Robbie, do you pre-soak your wet paper? The autobody guys all swear by putting your papers in water overnight before sanding! One of those "high dollar" painters told me he adds a few drops of glycerin to his sanding water. He claims it acts as a lubricant and lets the paper glide easier. Here's my tip on sandpaper. Grab a scrap of plush pile carpet. Use it to brush all the kernels and buildup. You'll find your papers last longer!

    Great video. I recently got a 1964 kono classical guitar from japan. I has a fretboard crack, which upon several months of proper humidification has closed (no gap). I see a lot of people repairing these cracks with superglue and sawdust, as a void filler kinda like what's shown here. I get that. I have good experience fixing soundboard cracks with hot hide glue and love how it vanishes as it pulls joints together. I am considering repairing this fretboard crack with the hot hide glue, as it has closed nicely upon proper humidity (it doesn't need filler); rather than using the more popular superglue. Is there any reason I shouldn't use hot hide glue on a fretboard crack?
