I get by with virtually no effects pedals.

If I'm playing with a non-master volume head, then obviously I need a distortion or overdrive pedal.

Other than that, for what I do the only other one I'd need is a volume pedal.

In addition to volume, I always use a tuner, but wouldn't necessarily need it inline during a gig. If a guitar gets so out that I can't tweak it quickly back by ear I tend to abandon it in favor of something tuned and ready in reserve.

So, if we've excised "tuner" from pedals, I only really need a disstortion and volume pedal.

This leaves me 3 more in an ultra-lux scenario. In that case, I'd choose a good analog delay, a chorus, and maybe a reverb. Last place is really a toss-up though. If not a reverb, then a wah-wah or phaser. But of those 3 for the final slot, a reverb, at least for what I do in the 2 side bands I'm in.
