Walrus Audio Slo VS Fathom (Comparison)
Our pick: The Walrus Audio Fathom
Though both pedals are extremely similar, it's the fathom that impresses us a little more with a fourth algorithm and a little more versatility. Though the argument absolutely comes down to personal preference. How many hairs do we need split here?
From a tone perspective the Slo is a little, well...slower. It uses more subtle algorithms that allow you to slow down the rise of the reverb and create more of an emotional, layering ambience. The Fathom can do this too, but also has a more conventional side of reverb tones, and is capable of a wider range of ambience. Both pedals are good, but we like the Fathom just a little bit better.

Pricing is exactly the same. And the basic specs comparison doesn't tell you much either. Both pedals are digital, though the Fathom gives you that extra algorithm and perhaps a bit more control. Both also have the sustain switch.

These demo videos put out by Fathom are exceptionally good. A lot better than most of the third party demos (including ours). So we'd recommend starting here, just to get an idea of which tone profile you prefer. Both pedals are so good that it definitely comes down to more a matter of tone likeability than anything else.
Comparing Spec Sheets
The Fathom adds in the modulation switch, which again helps to give you some more conventional sounds and more balanced approach to reverb. The program knob (instead of a switch) allows you to select between your four algorithms. Otherwise, there aren't a lot of spec sheet differences between the two pedals.

Walrus Audio Fathom VS Slo. What's the difference?
Which one is better?
We like the modulation in the Fathom and the array of tones that we were able to pull from it. But that's not to say the Slo isn't just as good. It's more subtle and perhaps a more emotional reverb, but that's an issue of preference and not quality. Whatever Walrus Audio does, they seem to go for it 100 percent, so we'd recommend either of these reverb pedals with confidence.
