I seem to have reached a speed limit.
Not looking for mega shred type speeds, but the ability to do quick flurries.
16th notes at 90bpm seems to be my limit. No matter how long or often I practice with a metronome, going back to slower speeds then moving back up, my limit is reached.
Any tips and tricks to get me through this limit? I've trained myself such that my fingers bearly leave the fingerboard, so flying fingers is not the problem.
Or has 30 years of playing the blues come back to bite me?
