I practice with a metronome so I know that I cannot play sustained 16th note lines any faster than 108 BPM. You should try it with a ‘nome, you might be unpleasantly surprised.I picked the highest option just to make the OP question his own abilities. I don't think I'm the only one.
I have no idea how fast I can play. Do many bass players sit down to try and work this out to a number? Why?
But because I studied banjo and adapted that thumbpick and fingernail technique for bass, I might actually not be lying.
