Thanks for all the supportive replies, I really do appreciate it.
I found that my deficits, other than falling over ~ a lot ~, I mean bass-related, are mainly with my middle two fingers, one of them possibly from overuse in a non-musical mode, and with accuracy and speed.
Imagine a crappy old car, we have all had one at some time in our lives, that has an accelerator that lags, and brakes that have about zero pad left and a low fluid reservoir. That is how my left arm and hand work now.
I have not had to look at the neck of my bass while playing since I was in my late teens, but I do now. If I want to quickly go from say the third to the tenth fret, not only is there a delay in my hand and arm starting to move, but also I overshoot almost every time, looking or not. That is my brain taking longer to find a new path to get the stop/go messages where they are supposed to go, typical stroke deficits.
The good news, my strength is OK, not perfect, but adequate, and I can fix that. I get a lot of physical therapy, and my therapist was thrilled that I played, and said it was a great rehab tool. She even uses those finger strength spring loaded devices you see in all the music shops for her patients.
Anyhow, I can see marked improvement since the stroke and think I will get a lot of what I lost back over time. In the mean time, less Rush, Yes and Dream Theatre, and more Tom Petty, Cars and Deep Purple...
AND AN APOLOGY:
For years I have mocked all the "Weight?" guys and girls who just had to know the weight of any bass of sale down to the ounce. I thought, "How silly, it doesn't make that much difference."
It does; to some, I was wrong, so I'm sorry for the snarky posts. (Karma sucks. right?)
