"Heeeyyy" in my best Fonzie...hmm...
that's showing my age.
"Thumbs up for Christmas!" Well in fact this is more about how I've been shaping my right thumbnail for a while. I've spoken about nails before but this is a new trick that is working well for me.
A problem I had was my right thumbnail being so long that when I bring my hand down real low to the fretboard and I really dig in, my nail will catch hold of the string, pulling it up and for a loud awful slap bass sound, it's not good.
I want some thumbnail length for the tone I like, so I had to have this perfect thumbnail length balance between long enough for tone and short enough that it doesn't catch.
So I put two and two together - have the left side of my thumbnail short so it doesn't catch, leading up to some length on the right side for the tone I am after! It took me a while to get over having a non-symmetrical shaped thumbnail (okay, I'm still getting over it) but not only did it cure the thumbnail catch problem, but I think it has improved playability and tone at the same time! It's only a minor difference but you end up with the correct attack angle for all positions - when I'm low down palm muting the strings, or when I'm high up classically picking.
I recommend giving this a try, I'm giving it a thumbs up <groan, thanks dad...>
