In this song “I’ll be Your San Antone Rose”, the 5th measure is giving me trouble to replicate the sound.
Bass starts in 2nd measure
2nd measure = D-A root-fifth
3rd measure = D walk up to (C#-B) to A
4th measure = A-E root-fifth
5th measure sounds like A-Open E-G#-Open E - G (vibrato?)
6th measure = E-B root-fifth
What is the bassist doing in that 5th measure to get that wavering G sound?
