Strings, technique, plectrums, amps, pedals. They all play a huge part in tone and that's especially true of rock bass.
When I researched my soul bass book, it was evident that most of that bass tone was down to the dark textures created by flatwounds plus a Fender Precision bass.
Rock bass players tend to go the other way, brightening the sound.
See how in the video below.
Rock Bass Tone
Rock is a huge genre and there are many rock bass tones that sound great.
Generally, rock bass players like:
- Bright sounds, so think stainless steel strings.
- Overdrive, distortion, and/or fuzz.
- Tube amplifiers (although you can use any amps and have your pedals provide the rock).

Certainly, being able to sound authentic in whatever style of bass you are playing is a worthy goal. Get yourself an overdrive pedal or two and you'll be ready to rock!
