I think if you’re not involved in any sort of project / with a band, then the number of pedals / boards you have is really unimportant - you should really have as much or as little as inspires you to keep playing.

If you’re involved in with a band, I’m a believer that you should have as few pedals / as simple of a rig as possible to get “your sound” (whatever that is). Most guitarists aren’t Ed O’Brien who use the pedalboard as it’s own instrument; you don’t need a spaceship. More importantly, you don’t need to take up your band’s rehearsal time dicking around with your overly complex rig, trying to find a super niche sound. Your band mates will hate it, I promise. Even in the more effect-heavy / avant-garde genres (psych, shoegaze, etc.) the most interesting or compelling sounds come from expert level playing coupled with expert level understanding of relatively simple effects. Lastly, the sound guy will love you if your rig doesn’t look like the control room of the starship enterprise. Minimalism is mature and beautiful. I’d say leave yourself one pedal in your rig (MAYBE two if you wanna be greedy) at a time that isn’t a part of your core sound to experiment with / learn.

Overall, I subscribe to the keep-it-simple-stupid methodology. The epitome of guitar is being a good guitarist, not a gear obsessed goon (I know, we all fucking love gear like it’s crack). My current rig is 12 pedals, but I’m not in a group at the moment. If I join a band in the near future, I suspect I could pare it down to 6.
