I wouldn’t add anything else, pedal-wise, in your input signal chain, at the risk of losing “your tone” but realize that you might have to make some adjustments in order to give each instrument, and your bass, its “sonic space” vs “mud” in the mix.
Things to try:
- make sure you’re getting enough high frequency content to work with either by DI or Mic’ing. If you end up not having enough you’ll have to add it/change your tone to get it. It can’t be added back in later, but it can be removed via EQ in your DAW.
- make sure you don’t over-compress your input signal. Need to have enough dynamic range to work with on the stem
- use an RTA to look at your primary spectrum, then layer a parametric EQ underneath, add a boost peak and sweep the spectrum looking for the key frequencies that make your tapping “pop” - this is where you’re going to want to focus your attention. You know how with kick drum there is significant high frequency content above 3k? Bass also needs HF content to “pop”
- EQ the other instruments out of this range, or lessen them enough to give the upper range of the bass some room. Use a combination of parametric EQ, high-and low-pass filters on each instrument stem to ensure there’s minimal spill outside it’s assigned slot in the spectrum.
- level the individual instrument dynamics with pink noise & compression, and use some mix bus compression to glue everything together
- Perhaps try to mix the bass first, then later other instrument stems on top to make sure it stays prominent in the mix.
- listen to your recording on some small speakers lacking much bass response. You should be able to still hear your tapping in the mix, along with the drums, guitar, vocals etc. If you can’t hear it then re-EQ and re-mix to ensure it’s there. Then work your way down the frequency spectrum.
- listen closely to some reference tracks to see how they are mixed. If you find one you like, use a program similar to iZotope Music Rebalance to isolate the bass/guitar/drum stems and listen to them. I think you’ll be surprised how “thin” the tone actually is, and how they are EQ’d. Things always sound different in the mix, and the tone you recorded in your head
/played live may need to be quite a bit different in the final mix. After EQ, compression and mixing an individual stem may seem thin and weak but placed in the mix it fits perfectly while retaining the tonal information you want.
Good luck!
