I played chords on bass a lot when I was in a band with one guitarist and I was usually driving the melody, but like Peningtron mentioned, it was usually doing runs on the D or G with respectively either the G or D open and ringing, or on the D with the A open. Occasionally would do some stuff playing two note chords on the D & G with the A open and ringing.

Definitely gets wonky doing chords involving the E, or anything below the 7th fret (in standard tuning), and once I played with guitarists with a fuller sound (or two guitarists) I started doing it less and less, and actually started playing more "real" bass.

I play a lot of chords on the bass too, or rather two-tones. Fifth, minor and major thirds and stuff like that. Nothing wrong with that!
And I play with a pick most of the time, not that there’s something wrong with finger style.

For recording bass, I make my own special picks out of a super special secret material.

Different tools for different jobs. I use both. Probably lean more towards raw fingers for bass but it totally depends. All techniques are valid, no judgement.

The only way to achieve any sort of accuracy and power, for me, is to use a pick. It lets me almost sound like I know what I'm doing.

My fingerstyle game on bass is weak and practically nonexistent. Sometimes I might use my thumb on a mellower, slower part, but it's rare.

Neither style is crap, but using a pick is my preference. WF for picking with a brand new set of DR Hi Beams, which is just too much clank for me these days. Use that magical thing called the tone knob for a month or so until the strings start to mellow out a bit, then it sounds perfect.

These days I use any technique that makes sense in context. I do love playing with a pick, partly because of the sound and partly because it requires the least amount of brainpower, and sometimes it's fun to be dumb.

There's a time and a place for both! Yes to all of it.

Both have their place. I usually play with a pick, but also like to mess around without one. Didn't have callouses under the thumb on my right hand until a few weeks back.

You been playing bass with thumb and fingers?

With the non-fretting hand? Yes.

Is this some kind of no-no?

Only, like, just started playing the thud staff, aside from messing around with bandmates' ones in the past, and in a music elective toward the end of h.s.
