If you’re a guitar player looking to be able to cover bass parts (or bass range parts) while still playing your regular 6-string guitar, consider the Boss Super Octave pedal. The Super Octave has a unique “Range” setting that allows you to specify exactly which notes on the fretboard will be processed with the octave effect. So you can, for example, limit the octave effect to the first 10 frets on the low E string. This allows you to chord and solo on the notes higher than the specified range without muddying the waters with a lower octave, while still getting that huge octave sound when you want the bass reinforcement on the bottom notes.
