Year Started Playing: 1979 - I learned the riff from Black Dog - that was probably a bit ambitious for a total beginner - managed it though.
Number of basses: 5 electric, 1 acoustic
Music theory: 3? I can't read dots (a stave ?) - I know if I'm playing in a major or minor key...I know what a pentatonic scale is. I struggle with remembering the intervals associated with modes
Technique: 2? I can only play with my fingers but I think I manage OK with that, muting with both hands - I used to use a pick some of the time but not anymore - I have nerve damage in my neck and right arm and hand which severely limits the grip strength in my right hand - I can no longer hold onto a plectrum for more than a few seconds. I have never been able (nor wanted) to slap.
Groove: 3 - I don't think groove is particularly relevant to the music I play. Yes I can keep time and get tight with the musicians around me but to groove needs some swing, doesn't it? My drummer doesn't groove at all, never gets funky. I suspect with a different drummer I might groove more but it's not really our style. I can lock in with him though but I wouldn't call it grooving.
I suffer from imposter syndrome big time.
