+1 on what’s been said above by itu and Al Krow. A good multifx pedal will help you decide which, if any pedals you’ll need/want.
In my case I’ve had pedals of all sorts for years yet only ever gigged them a handful of times. I guess it depends on the style of music you are playing, whether it’s original or covers and how faithful you want to be to that particular sound.
It’s a lot of fun trying them out though!
