A rig got 2 opinions.

"The rig starts strong with a Fender Stratocaster and Vibroverb, but the placement of the Ibanez TS808 before the Dunlop Univibe creates a tonal bottleneck. The TS808 is designed to work best with the natural characteristics of the amp, yet putting modulation after overdrive can muddy the signal and obscure the clarity of the Univibe's effect. A better approach would be to place the Univibe before the TS808, allowing for a cleaner modulation effect that retains the definition when overdriving the amp."

"Alright, let’s take a look at this rig. You've got a Fender Strat through a Vibroverb, which is a classic combo for clean, punchy tones. But throwing an Ibanez TS808 in front of it? It’s going to push that clean headroom just enough to muddy things up, especially when you crank the gain. The Univibe is great for atmosphere, but between the overdrive and the modulation, are you really going to find a slot in the mix for that lush swirl without it getting lost? You might want to rethink that order if you're aiming for clarity."
