@bobtoombs Welcome to BassBuzz!
When you have time, join us on the Introduce Yourself thread.
I sometimes play like this. Not specifically one finger per string, but thumb, first, and middle finger. It depends on the song. The vast majority of the time I play alternating first and middle.
There is nothing wrong with having the one finger per string ability in your arsenal. However, I have to agree with @howard, it doesn’t offer the same versatility or speed of playing as alternating first and middle finger. Also, the entire course is built around playing with alternating first and middle (with the exception of the slapping module)
Maybe @JoshFossgreen will have some different insight.
@PamPurrs Who would possibly give you a hard time about floating thumb style? Do they just not understand what it is?
