EarthQuaker Devices has spent twenty years convincing us that reverb doesn’t have to sit politely in the background. Afterneath sent drips cavern-dwelling. Astral Destiny went cosmic. Transmisser just… floated off somewhere. Now comes the Towers, labeled as a Stereo Reverberant Filter. Jamie Stillman is very clear: this isn’t an evolution of anything they’ve done before. It’s a “linear progression,” which translates roughly to “we built something new and we’re not telling you exactly how it works.”
Here’s what we do know. Your signal enters an array of infinitely repeating micro-echoes—think of them as architectural scaffolding for sound. Those generate impulses that feed a massive cathedral-style reverb. Then a resonant low-pass filter intersects the whole mess at multiple points, like someone running a synthesizer through the plumbing of a concert hall. The result isn’t reverb. It’s a soundscape generator.
The three algorythms give you different ways to navigate:
- Manual puts you in charge: twist the Frequency knob and the left channel moves opposite the right, creating stereo movement that’s actually physical rather than just “wide.”
- Envelope mode turns your picking dynamics into filter movement -play harder, the frequencies shift. The Frequency knob becomes sensitivity control.
- LFO mode surrenders everything to a slow oscillator that sweeps across the stereo field while Frequency becomes rate control.
Then there’s Stretch. Hold that footswitch and the whole digital system slows down. Double the reverb length. Frequency spectrum shifts. Pitch bends throughout the morphing process. It’s lo-fi in the best sense – not degraded, just… pulled apart. Pleasant inaccuracies emerge. Artifacts spawn. The thing descends into the abyss and takes your signal with it.
Eight user presets because you’ll find settings worth saving. True bypass, 85mA draw, $299. Built in Akron, Ohio, by people who apparently understand that reverb shouldn’t just decay – it should radiate, breathe, and drift endlessly into whatever void you’re currently staring into.
