Bearing Edges
The bearing edge is the surface where the drum shell meets a drum head. How and where these surfaces meet can determine most of a drums sound, response, and flexibility. Bearing edges are the single most important factor in a drum. They're responsible for tuning range, stability and intonation, as well as feel. Regardless of shell type, suspension systems or any other upgrades, a proper edge will have the largest influence on the over all tune-ability, sustain, overtones, stick rebound and even head life. With ten years of re-shaping edges I've learned one main lesson. The largest difference between good drums and bad...are the edges.


Edge Service
Poorly shaped edges come with many frustrations. Most of these problems are buzzes at low tuning, uncontrollable over-tones in the high register and a flat stick response. Not to mention the classic cry, "I can't get this drum to tune!"

We offer an alternative to the moon gels, duct tape and heavy drum heads while adding a larger tuning range and clearer tone. With several edge types to chose from, we can adapt your current kit to fit your new needs.


Edge Types

Full round
- Warm and punchy with a slightly shorter decay. The greater contact between head and shell, transfers the heads energy into the shell and amplifies the wood tone and character. This hand drum type edge was made famous by the original Yamaha Recording Custom. This edge works perfectly in the studio due to its shorter sustain and warmth without using muffling devices that remove volume, tone and dynamics. This is the default bearing edge on all Kirsch kits.

Double 45 degree - Bright, open and loud with a long sustain. Double 45 works well for brush work, players with a lite touch, or folks who like a lot of ringing overtones. This edge is considered the modern sound.

Round-over to 45 degree - The best of both worlds, this edges combines some of the warmth of the round-over on the outside with the openness of the 45 degree at the playing surface. This is the most versatile and user friendly edge.

About the single 45 degree - We do not recommend the single 45 (or 33) degree edge. Although it has become the industry standard, it's a terribly flawed design in our book. This edge creates too much outside diameter for all drum head brands and causes the head and shell to fight each other. Due to the minimal labor and skill required, this edge has become very popular with most manufactures. In my personal opinion this cheaper, faster and easier to produce edge is the worst thing to happen to drums since mass production began. Click here to check out the Kirsch drums blog for more info.

Vintage Edge Service 
Many companies that are known for a certain sound, have become known due in large part to their edge types. Over the years these edges have changed because of new ownership and designers, changes in manufacturing tools and locations, and many other reasons. Some brands have even gone through three or four edge profiles. For example, Gretsch used a fully rounded edge to create that "Great Gretsch sound", and then moved to a sharp 33 degree cut. Camco and early DW edges were rounded on the outside and they also moved to a sharp edge. These drums can be restored to the original manufacturer designs and returned to what made them sought after legends. With years of research I've developed era specific bearing edge reproductions. In the case of Ludwig and Slingerland, we had to make special bits to reproduce tooling that is no longer used. This dedication to detail and history has made Kirsch Drums the trusted choice for restoring vintage drums or returning modern drums to the makers original sound concept. We can also restore drums that have been modified, back to the original manufactures edge. The vintage service also includes restructuring of reinforcement hoops, shell gaps and cracks and dry-rot.

 Modded Edge Service 
In most cases, re-edging a kit won't change the character of your favorite brand. Edge restoration generally adds more control and easier tuning over that character but doesn't make one brand into another. We can "mod" certain brands to be vastly different than their original design. Personally, I don't recommend these types of changes as they can lower the value of a kit. If you need a largely different sound, you may want to consider another drum set. All that being said, if you need something really different than your current sound without buying a new kit, modded edges are available.

Do I need edges?

If you've had problems with wild over-tones, buzzes or wrinkles in the heads or an inability to tune low, you're likely in need of new edges. There is one test you can do to find out if you might need edges. Remove the heads from your trouble drum and find a flat as possible surface. This is called a level test. If the drum rocks back and forth on this surface, your drum is missing some low end tuning range and control. Cracks ,chips and gaps can also cause issues. As mentioned earlier, a single 45 degree edge can also cause a lot of missed potential. So look for that as well.

Like a guitar, bass, piano, violin, or any other acoustic instrument, drums need an adjustment to get the most out of them. Even fresh from the factory, most production drums can benefit from an edging. Many guitar players will have a set-up done on a guitar, right out of the box, even on the highest end model. While a guitar with a bent neck is almost useless, a drum will still produce... something many drummers don't realize how much potential is missed. Folks who struggle with tuning and tone, don't realize the instrument isn't tunable. Every time I hear, "I'm not good at tuning" I say, "It's not your fault". Fortunately for us drummers, we only need one set-up for the life of a kit.
