Our God- decaying delay on the verses
Cornerstone- delay on the turnarounds, octaver on the up-choruses at the end
Oceans (where feet may fail)- deep chorus throughout (with the "speed" turned off), then add octaver on final building bridge
Rez Power- filter on the pre verses, turnarounds, and outro
Manifesto- overdrive on the intro & choruses, reverb in the verses, Meatbox (subharmonic) on the bridge, fuzz on the final chorus & end
Let It Be Known- octaver and chorus on throughout, added overdrive for intro & choruses, massive slide down the E string with the Meatbox going into the bridge
You gotta be creative. My favorite thing to do is to embellish something as straight as a Chris Tomlin bass line with well-thought-out, tastefully applied effects to bring a new dimension to the song. Odds are the bass lines we're all supposed to be playing are VERY straight (hillsong, elevation, Tomlin, Jesus culture, etc) and the first instinct is to drop some sick fills where we can, or, (God forbid) start slapping (please don't ever start slapping lol!). I've found a better way to add "more" without "noodling" and losing the groove is to really think about where a well-placed subtle effect will elevate the overall mix.
You also REALLY have to know what your effects do and intentionally apply new sounds. Although I've been guilty of this MANY times, it's not always a great idea to just kick on the newest, funnest toy.
Specific settings are VERY important.
I know exactly what my chorus is gonna sound like when I hit it: I intentionally set it so I get a very "deep shimmery/watery" sound but with absolutely no "warble" at all.
A momentary stomp on my Meatbox for something as quick as a big slide into a bridge really replicates an 808 drop quite well
My octaver is set to unity volume with my dry sound, so I'm only adding lower tones to really fill up the sound, not more output or a "louder" feel (although turnin the dry octave off and pegging the octave-down really is fun sometimes!)
My delay, which I use quite a lot, is set to decay after only about 4 or 5 "trailed" delay'd notes that get quieter with each repeat, so it never lasts long enough to throw off the actual groove. (Gotta LOVE tc toneprint technology!)
I am BY NO MEANS an expert, I just think through every thing probably a little too much. I have DEFINITELY been guilty of overdoing it, but I have stumbled upon quite a few things that work!
