Closed Reed Selection Guide
An intermediate closed-reed builder guide covering cottontail and jackrabbit starting points, medium and loud voice reeds, single and double designs, Sample Reed Kit 002, the 40-reed sampler, direct insertion, sleeves, bushings, body materials, tuning, moisture testing, and bulk-buy decisions.
Closed reeds come in hundreds of variations, and the finished call cannot be selected from the reed label alone. This guide turns a complicated catalog into a controlled test process built around voice family, mounting, body, tuning, and repeatable sound.
How Do You Choose A Closed Reed For A Predator Call?
Choose a closed reed by starting with the finished sound and then testing several reed families in the same call body. Thinner medium-voice single reeds are useful starting points for cottontail-style distress. Thicker loud-voice single reeds and double reeds are useful starting points for jackrabbit, larger-prey distress, and some coon squallers. Those are not rigid labels: many builders use the same reed model for different calls because a small tuning bend, body design, mounting depth, sleeve, bushing, or double-reed combination changes the final voice. Use a sampler before buying bulk and document the complete build that produces the sound you want.
Closed-reed selection looks simple because the reeds arrive as ready-made metal assemblies. The complexity appears when a builder realizes just how many voice, material, single/double, size, and tuning combinations exist.
The solution is not to memorize every model. The solution is to build a repeatable comparison method.
The Closed-Reed Selection Framework
This process separates what the reed contributes from what the rest of the call contributes.
Cottontail Reed Starting Points
For a classic cottontail-style call, a thinner single reed with medium-voice or medium-volume characteristics is a useful place to begin. The reed tends to start easily and can produce a responsive prey voice without requiring the strongest air.
That does not mean every cottontail call should use a medium reed. A loud-voice reed can be tuned and installed in a body that produces a raspy cottontail character. Many commercial builders use unconventional reed/body combinations that work because the complete call is tuned around them.
Use the medium/thinner rule to narrow the first test group, not to end the experiment.
Jackrabbit And Large-Prey Reed Starting Points
Thicker loud-voice single reeds and loud-voice double reeds are useful starting directions when the goal is stronger output, deeper body, or heavier rasp.
A jackrabbit call often benefits from a reed that remains stable with more air, but the call body must support that pressure without becoming excessively restrictive.
Double reeds can add texture and complexity, which is useful for rough distress voices and some large-prey or squaller-style designs.
Why Reed Labels Are Not Sound Guarantees
Reed manufacturers need names and model numbers to distinguish components. Call builders need names to describe finished products. Those two naming systems do not map perfectly.
Builder A may call a tuned loud-voice reed a cottontail because the finished body produces a medium raspy prey sound. Builder B may use the same reed straight or with a different body and call it jackrabbit.
The correct definition is the sound the finished call makes, not the animal name someone attached to the component.
Single vs. Double Closed Reeds
| Design | Sound Character | Air / Fit Consideration | Good Starting Use |
|---|---|---|---|
| Medium single reed | Clean, responsive, moderate voice | Usually easier starting air | Cottontail and general prey |
| Loud single reed | Stronger, fuller, more air capable | Needs body that supports stronger flow | Jackrabbit, raspy prey, large fields |
| Loud double reed | Rasp, complexity, less uniform tone | More variables and alignment | Jackrabbit, large prey, squaller experiments |
| Two separate reeds in bushing | Layered/custom combinations | Requires two-hole mounting and careful matching | Experimental squallers and custom voices |
Do not assume double automatically means better. A single reed is easier to diagnose and can be tuned into a very useful raspy voice.
Start With Sample Reed Kit 002
Sample Reed Kit 002 provides a broad group of commonly used reed models without forcing the builder to purchase large packs.
| Model | Quantity | Category To Compare |
|---|---|---|
| LV-002 | 2 | Loud voice single |
| LV-003 | 2 | Loud voice single variation |
| LV-025 | 2 | Loud voice single variation |
| MV-025 | 2 | Medium voice single |
| LVDR-002 | 2 | Loud voice double reed |
| LVDR-025 | 2 | Loud voice double-reed variation |
| MV-002 | 2 | Medium voice single variation |
| Reed sleeves | 2 | Sleeve-mounted installation |
The kit contains 14 reeds across seven reed models plus two sleeves. Use one body, install each candidate consistently, and record the sound before tuning.
Use The 40-Reed Sampler When You Need Repeats
The 40-Reed Stainless Steel Sampler contains ten each of MV-025, LV-025, LV-002, and LVDR-002-002.
It is valuable after the builder wants to compare several copies of the same model, tune some while leaving others stock, and build repeat calls with the winning setup.
The pack is designed around reed families commonly used for cottontail, jackrabbit, and larger-prey distress.
Choose The Mounting System Before Finalizing The Reed
| Mount | Advantages | Body Requirement In The JC System | Service Notes |
|---|---|---|---|
| Direct insertion | Simple, few components | 7/32-inch hole | Reed seats directly in body |
| Metal sleeve | Serviceable, controlled reed seat | 9/32-inch hole for JC sleeve | Reed can be replaced without changing body hole |
| Single-hole rubber bushing | Flexible serviceable mount | Use bushing-specific body fit | One reed |
| Two-hole rubber bushing | Allows two-reed experimentation | Use bushing-specific body fit | Two independent reed positions |
Mounting depth and seal can change response, so do not compare one reed direct-fit and another in a sleeve and assume the difference comes only from the reed.
Keep One Test Body As Your Reed Bench
A dedicated test body is one of the best tools a closed-reed builder can make. Use a serviceable sleeve or bushing system and a consistent bore so multiple reeds can be compared quickly.
Recordings from the test body help identify which reed families deserve further experiments in acrylic, horn, or finished custom bodies.
Once the winning reed moves into the final body, expect some change and retune only if needed.
Use Tuning To Refine, Not Rescue
A closed reed that is already close to the target voice is the best tuning candidate. Add a very small upward bend or taper, then test.
If repeated bends are required to make the reed acceptable, stop and try another model. Over-tuning a poor match is slower and more expensive than selecting a better starting reed.
Final Body Material Can Change The Winner
Acrylic provides a consistent machinable body. Natural horn can vary in wall thickness and internal geometry. Those differences can change resonance and back pressure.
If the finished line will include several body materials, test the leading reed in each body family before assuming one recipe fits all.
Browse Acrylic Call Bodies and Cow & Steer Horn.
Coon Squaller Selection
Coon squallers often use stronger closed-reed families similar to reeds used in loud jackrabbit calls. That makes loud single reeds and double reeds reasonable places to begin.
But squaller body design matters heavily. A reed that produces an excellent jackrabbit in one body can produce a very different aggressive squall in another.
Do not label the component as a “coon reed” until the complete squaller has been tested.
Closed-Reed Selection Must Include Low And High Air
| Test | Why It Matters |
|---|---|
| Soft start | Shows whether the reed can be used in heavy cover or close range |
| Normal medium air | Shows the everyday hunting voice |
| Strong air | Shows whether the reed can project without flutter or distortion |
| Repeated calling | Shows moisture and heat behavior |
| Cold restart | Shows whether the assembly is dependable for winter hunting |
| Hand cup | Shows whether body resonance can add useful variation |
When To Buy Reeds In Bulk
Buy bulk after the reed has survived three tests: it sounds right in the target body, it remains dependable through repeated calling, and the tune can be reproduced on more than one sample.
A reed that sounds perfect once but cannot be repeated may be the result of an accidental bend or unusual sample variation.
Build two or three copies before committing to production quantities.
A Practical Closed-Reed Selection Rule
Medium/thinner singles are strong cottontail starting points; thicker/loud and double reeds are strong jackrabbit starting points. The finished call determines the final sound.
Selection Process: Choose A Closed Reed For A Predator Call
Use this process to start from the finished voice, narrow the reed family, hold the test body constant, compare samplers, tune only after the stock test, and document a repeatable final recipe.
Define the finished voice
Choose the sound character: cottontail, raspy cottontail, jackrabbit, large prey, coon squaller, or another custom distress voice.
Choose a starting voice family
Medium/thinner single reeds are useful cottontail starting points; thicker/loud voice reeds and double reeds are useful jackrabbit or larger-prey starting points.
Choose single or double reed
Start with a single reed for a cleaner baseline or a double reed when additional rasp and complexity are part of the goal.
Choose a mounting system
Direct insertion, metal sleeve, single-hole rubber bushing, and two-hole bushing all affect serviceability and fit.
Keep the test body constant
Use one known body and air path while comparing reeds so the reed variable can actually be heard.
Use sampler packs
Compare multiple reed models before purchasing bulk quantities.
Tune only after the stock comparison
Add a tiny upward bend/taper only when a specific reed is already close to the target voice.
Test repeated sequences and moisture
A closed reed must stay dependable after several minutes, not just produce one good first note.
Document the winning recipe
Record reed model, body, bore, mounting, tuning, and final sound name.
Common Closed-Reed Selection Mistakes
Closed-reed catalogs become manageable when the builder stops treating voice labels as final call names and starts comparing one controlled variable at a time.
Treating Medium Voice As Cottontail And Loud Voice As Jackrabbit Absolutely
Those labels are useful directions, not fixed animal-sound identities.
Comparing Reeds In Different Bodies
Body changes can be larger than reed changes, making the comparison meaningless.
Ignoring Double-Reed Interaction
Two reeds add complexity and require alignment, fit, and enough air path.
Buying Bulk From A Product Name Alone
Sampler testing is cheaper than discovering that a bulk reed does not work in the chosen body.
Over-Tuning A Poor Starting Reed
If the reed requires large bend changes, choose a different model rather than risking damage.
Ignoring Serviceability
A great-sounding reed can become frustrating if the body design makes replacement or cleaning difficult.

These answers cover cottontail and jackrabbit starting reeds, double reeds, sampler contents, test bodies, sleeves, tuning, bulk buying, and why reed labels do not define the final call.
A thinner medium-voice single reed is a useful starting point, but tuning and body design can make many different reeds work.
A thicker loud-voice single reed or double reed is a useful starting point for stronger jackrabbit and larger-prey sounds.
Yes. Different bend, body, mounting depth, and air system can move the same reed into different finished roles.
They can add rasp and strong output, making them useful starting choices, but a tuned single reed can also produce an excellent jackrabbit call.
It lets builders compare 14 reeds across seven reed models plus two sleeves without purchasing bulk quantities of each.
Ten each of MV-025, LV-025, LV-002, and LVDR-002-002.
Yes. Keeping the body constant makes it easier to hear the actual reed difference.
They can change fit, insertion depth, serviceability, and the complete call's response, so keep the mounting method consistent during comparisons.
Direct mounting inserts the reed into the body; sleeve mounting inserts a metal sleeve first and the reed into that sleeve.
No. Hear the stock reed first. Tune only when a small refinement is needed.
After the reed works in the final body and the result can be repeated across multiple samples.
