Filter Modules by the numbers
Measured across all 103 models in this category, so «wide», «short» or «expensive» mean something you can check.
How to Choose the Best Filter Modules
Filter Type
Moog-style ladder filters are your bread and butter for that fat, warm, resonant low-pass sound. State Variable filters offer more flexibility with simultaneous high and low pass outputs. Knowing what you want-a creamy pad, a searing lead, or something in between-will guide your choice.
Resonance Control
This isn't just about screaming feedback; it's about adding character and movement. A good resonance control offers a wide range, from subtle thickening to self-oscillation, and should respond predictably to modulation.
Modulation Capabilities
Can you modulate the cutoff frequency with envelopes, LFOs, or even velocity? This is what breathes life into your filters, allowing for dynamic movement and expressive textures. Look for CV input jacks and ideally, attenuators to dial in the modulation depth.
Steepness/Slope
The slope determines how quickly the filter attenuates frequencies. A steeper slope (24dB/octave) is more aggressive and useful for dramatic filter sweeps, while a gentler slope (12dB/octave) is smoother and more subtle.
Drive/Overdrive
Many filters offer a drive stage that adds harmonic distortion. This can be used to add warmth, grit, or outright fuzz, but be mindful of how it affects headroom and overall mix clarity. It's easy to get carried away and muddy the sound.
Buying Guide
At this level, you're probably willing to spend a little more for quality. Avoid the absolute bottom-tier clones - they often cut corners on component quality, leading to noisy operation and unpredictable behavior. Focus on modules with solid build quality, a responsive control panel, and a clear, defined sound. Don't chase the 'latest and greatest' - classic designs often have a reason for their popularity.
How This List Is Built
We don't play these instruments — we're a catalog, not a review desk, and we'd rather say so than pretend otherwise. This page covers 103 filter modules from the Thomann catalogue, which is the largest single source of specification data in this category: 15 in detail, the rest listed with their specifications.
Position is computed, not curated. We parse the manufacturer's own description into actual values — nut width, scale, fret count, fingerboard radius, size, alloy — and rank on them: how many specifications a model has published, how many of them are measurable numbers, and how precisely it meets this page's criterion. A product image adds a little. Price is not a ranking signal: it tells you nothing about whether a neck fits your hand. The same inputs always produce the same order, so nothing here is shuffled to look fresh.
What this list is good for: narrowing a category down to a shortlist by spec and budget. What it isn't: a substitute for hearing an instrument. Before you buy, read hands-on reviews and, where you can, play it. Full methodology.
