How to Choose the Best Filter Modules
1
Resonance
This is key. A filter without usable resonance is just a tone shaper, not a filter. We're looking for that sweet spot where it self-oscillates, or at least screams convincingly.
2
Filter Type
Low-pass, high-pass, bandpass, notch - each has its place. We're assessing if the filter type is versatile enough for different sound design tasks, and if it delivers the characteristic tone you'd expect.
3
Slope/Order
Steeper slopes (higher order) mean more dramatic filtering. A 24dB/octave filter will have a much more pronounced effect than a 12dB/octave, and we're evaluating the sonic impact.
4
Drive/Distortion
Many filters benefit from a bit of drive to add warmth and grit. We're looking for modules that either have built-in drive or play well with external distortion sources.
5
Input/Output Level
A filter's headroom and signal level can make or break a patch. We're checking for noise floor and whether the module can handle hotter signals without clipping or getting muddy.
Buying Guide
At this price point, you're making trade-offs. Don't expect Moog-level build quality - the pots might be a little scratchy, and the case might be plastic. However, a lot of clever designers are squeezing incredible sound out of these budget modules. Focus on the core filter characteristics first, and don't sweat the minor cosmetic details. A little bit of external drive can often mask the limitations of a less-than-stellar filter design.
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 45 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.
Frequently Asked Questions
Absolutely. The value proposition is insane right now. You're not getting the absolute best, but you're getting a lot of character and functionality for the money.
24dB/octave filters have a steeper slope, meaning a more aggressive cutoff. They also tend to have more resonance. 12dB/octave filters are gentler and often more subtle.
Some noise is inevitable with budget components. Try to minimize gain staging issues and check your power supply. Excessive noise might indicate a faulty module.
Definitely! A resonant low-pass filter is a classic bass sound. Just be mindful of the headroom and distortion - too much drive can make your bass sound muddy.
There are a few modules that attempt to emulate the Moog ladder filter, but don't expect a perfect clone. Look for modules with a similar resonant peak and a characteristic 'fat midrange honk'.
