A really useful, albeit extremely basic, bass technique is hang on the root note of whatever chord you're playing bass over. Eighth notes works well.

Once you have that, finding places to go seems to start happening.

I'm no bass player, though. I don't even own a bass guitar. I just use an octave pedal to play one octave lower on strings G to low E.

I agree that the addition of Bass lessons would be good, and might even attract new members.
