Effect used on Led Zeppelin's "Nobody's Fault"

OK, it's obviously a phaser. I think it's a Phase 90 but I'm not sure. I don't know what year those came out, but I think the song is from 74. I play the song, but I want to invest in a phaser to nail the tone a little better. Will a Phase 90 get me there ? I don't want to be a tone perfectionist, I just want a good close to the original sound.

I've got a phase 90 script that really nails it , great for some Ted Nugent stranglehold too

Page used a Phase 90 for the live versions, but there's more going on in the studio version, where I hear more flanger than phaser. It's probably not a pedal, either. Page was notorious for studio trickery involving tape effects and mic placement.

So, if you're trying to nail the studio version, get a flanger. You may not "nail" it, but it'll get you closer than the Phase 90, IMO.

Actually I think it's "through-zero" flanging, which is a tape-based flanger effect. The most recent example that springs to my mind is when Lenny Kravitz used a similar effect during the pre-solo breakdown in "Are You Gonna Go My Way".

Some phase pedals might get you there, but in my opinion you're going to have better luck for that kind of dramatic sweep if you go the flanger route. Be sure to put the flanger after distortion or in your amp's effects loop for maximum impact. The pedal that springs to mind immediately is the TC Electronic Vortex flanger.

Page has a Phase 90 on his Cornish board. I use a Foxx Foot Phase. This is good if you want change up the sweep as you play. It will get you closer, but I think the 90 is easier to set and forget.

Kravitz used an (early vers.) Foxrox Paradox for the flange effect in "Are You Gonna Go My Way"

lefty73 is correct,

It's quite easy to discern between pedal based "flanging" and true tape flanging. The Led Zeppelin song used true tape flanging, and this actual effect is impossible to come by in a pedal form. Sure, you can get close, but nothing comes close to "Itchycoo Park", etc...

The pedal you are looking for is a Flanger. A Phaser was an early attempt at getting the flanged sound, but it technically is a different thing. The ideal way would be if there are any pedals (or floorboards) that allow you to control the sweep of the flange with a pedal. Tape flanging is irregular because it involved someone speeding and slowing down one of two signals. Current LFO Flangers have the sweep constantly moving at the same speed which is the dead give-away, and is much more of a sterile sound.
