Hey all, I'm new around these parts...been learning guitar for a while and switched over to bass. Loving everything about it! I'm using the Fender Play App to get going and it's been pretty great so far. A few questions are popping up. When playing with the thumb on the bridge pick up, is it bad to rest on the actual pick up rather than the black piece that it's sitting on? When I watch them in lessons, it seems they're always just on the black, but sometimes my thumb just goes to the pick up (silver) on it's own. I don't want this to become a bad habit, unless it's no big deal. Is the pick up in danger of loosening in time that way, and that's why they stick to the black bit? Or am I just overthinking it (quite possible!) Also, when resting the thumb on the strings, are only the E and A strings used for thumb placement? I tend to rest on the D when playing the G string, but again, haven't seem them do this. Overall, there seem to be a lot of things that my fingers are doing naturally, and still getting the right notes (this is very beginner stuff, of course). So I don't know if I should be working to correct these now. My assumption is that the placement suggestions they use are going to be more useful as things get more complicated, so I do want to pay attention.
