I tune mine at 72 for Blues, Jazz, Classical. 75 to 80 for Rock and Hard Rock.

Due to that 30 degree bearing edge, the resonance comes out long and clear which is needed for Blues and Jazz, without resonator rings or gel.

I use res ring or gel for all other types of music.

Another thing is that you can use mufflers and adjust them to your needs.
I'll be posting some vids real soon. I just hope that the audio is good.
