Second the Zoom multi nomination.
B3, B3n, something similar will give you a huge bang for the buck, for about the price of one dedicated pedal.
I highly recommend the Ovnilab Smoothie for a comp, but it will be $200 if you can find one.
The Zoom will have three or four comps to play with. You’ll get a feel for what you like or need in a comp. The B3 has a number of nice chorus effects, along with phasers, octaves, autowahs, dirt, amp models, cabs.....
Same with the other effects, plus you’ll get your tuner, beats, a looper, interface, di, and a boatload of other effects. It’s a Swiss Army knife for bass. A practice station with great headphone sound.
Most all my single effects have come and gone, except the smoothie. I work with a B3 or my line 6 HD500x and in ears.
For tuners, I like the mini headstock from planet waves.
