Disclaimer: I dont know much about amplifiers. I've been using my fender rumble 40 for rehearsals and live shows with my band. We're a 3 piece. Drums, Keys, Bass. The rumble was fine for practicing at home, but it struggles to keep up with live performances and some rehearsals if we work with guitarists or horn players. My main bass is an Ibanez EHB1005F & I frequently use a Zoom B6. Here are some songs that have a bass tone similar to what I'd like to make my main sound.
