I'm not an expert you understand, no really I'm not, but off the top of my head from what I remember: managing weight and balance, reducing fretting-hand tension, optimizing reach, breathing and performance anxiety.
Bit of a minefield. There's no 'regulation' just because someone is teaching bass doesn't necessarily mean they know about good technique. Plenty of teachers are great players who are passing on their own bad habits ๐
If i was paying someone to teach me some bass, minimum requirements would be theory, improvisation, and Alexander technique.
YMMV.
As an aside to this thread, remember these pedals don't come with a rule book. I have the one above (the only one from the range that Jack doesn't seem to have ๐) and last night at rehearsal we used it with the trumpet. The octave down setting made for a useable tenor sax sound, and the group setting made for a useable brass section type sound.
"I was at Eric Clapton's wedding when I joined the Beatles" Chas laughs.
"Me and the missus got invited an there was a marquee set up in the grounds with a stage, amps and drum kit in case anyone felt like getting up and having a jam.
"Anyway, this little kid started bashing the drums and called over to me saying "C'mon Chas, sing Gertcha for us". So I go up with the mic and started singing some rock and roll stuff. I looked up and there was Ringo sitting there smiling at me. The next thing I knew Paul was plugging in his bass and George slipping a guitar over his head. And there's me in the middle thinking "I'm the fourth flippin' Beatle here!"
Dress rehearsal for next weeks gig, so all using our own gear.

I had trouble with my sound all evening. Couldn't get it right it was always too toppy or clanky, or not bassy enough. The only thing that has changed is that my strings are now DR Neons (Christmas gift).
I finally got it right on the last song. Flat EQ but with the bass boosted to 4 o'clock. Spectracomp tone print on full.
