Alas, I cannot be a verified buyer as I wanted the Kamakura design and had to buy it elsewhere as I was late to the party. (Though I did get the Kamakura tremolo a few months back and loving it more every time I play with it.)
I normally use a Darkstar or an Afterneath, both of which I love for their mind-altering sounds and epic sonic vistas, but sometimes you just want a . . .um . . . mellower controlled substance. The Fathom is absolutely fantastic at being a general always-on reverb, but it has plenty more to offer if you want to experiment. I have no trouble bringing up a little extra shimmer and sparkle--that can often stand in for other effects that might not be on the board. And the modulation switch makes adding a smidge of gooey warble easy—and easily removed if things get muddy with other effects.
So the Fathom sounds great, plays well with other pedals, is tamable for more standard sounds/genres, but it also has plenty more sonic experiences to offer if you want to dive deeper.
(I also highly recommend the Lillian phaser. It's so good, I bought a second for my bass board.)
Hey Dennis! Thanks for the love. We appreciate you writing about the Fathom. Enjoy! - Walrus Audio
