Airlogic Bass Drum Pedals

Springless bass drum pedals return force is created by the compression of air. A pedal return force created by the compression of air provides a feel, control and response not possible with any spring pedal. The difference is due to the physical properties of a spring which react in a linear manner when providing a return force verses a non-linear or hyperbolic air return force. Airlogic bass drum pedals include the latest technology in adjustability and in their overall construction. They are designed, built and assembled in the United States of America from billet aluminum, brass and stainless steel.

How Airlogic Pedals are Different from Spring Pedals:

The main difference between Airlogic pedals and most other pedals on the market is that they do not use a spring to provide the beater return force. When an Airlogic pedal is depressed, air is being compressed inside a sealed cylinder, much like the piston and cylinder in an internal combustion engine. The build-up of air pressure provides the force to return the beater. The main difference between a spring return and the Airlogic pneumatic/air return is that a spring force is a linear function and the Airlogic air force is hyperbolic or non-linear. Every spring, expansion or compression follows the laws of physics that appear as a straight line on a graph when return force is plotted as a function of beater travel or beater displacement. The same plot for an Airlogic pedal produces a hyperbolic curve which translates to the return force building up in a non-linear manner resulting in much less force required by the drummer to over come the pedal return force, permitting momentum to assist in overcoming the return force build-up. This is the main reason that an Airlogic pedal can achieve very fast speeds with very little effort on the drummers part and at much lower resistance settings. This ergonomic advantage requires much less effort by the drummer and lends itself to playing many fast tempos and multiple note patterns using a heel down vs. a heel up technique, which is usually required with a spring pedal. The Airlogic pedal can be played heel up as well, no problem, however, it can provide the drummer the ability to play complex patterns without switching from heel up to heel down during execution. The fact that the return force in the Airlogic pedal ramps up quickly just before the beater makes contact with the bass drum head makes the pedal feel effortless, requiring less force to be overcome by the drummer as in a traditional spring pedal.

Spring vs. Air

The air pressure that provides the return force is totally adjustable by the drummer. Pressure can be added by moving the small pump ball located at the bottom of the air cylinder. By pushing this ball handle upward, additional air is introduced into the air cylinder, through a check valve and into the sealed compression chamber, increasing the return force or PSI (pounds per square inch). Air pressure can be bled out of the cylinder if too much pressure was introduced into the cylinder. This is accomplished by depressing the rubber ball located just below the miniature air pressure gage. The air pressure gage provides the drummer with data on the exact PSI the pedal is charged with to quantifying accurately the pedal calibration.

All of the air pressure adjustments can be made on the fly without any tools or drum keys. Once the pedal is at a pressure setting the drummer is comfortable with, the pedal will hold this pressure setting so adjusting the pressure can be a very infrequent event. In addition to the unique air return force, Airlogic pedals incorporate many other unique features. Each pedal includes an adjustable drive mechanism that permits the pedal to be adjusted from a true center drive configuration to two different cam configurations. Cams do not have to be replaced or interchanged to achieve these drive configuration changes. These changes are accomplished by making adjustments to the main drive hub and take only a few minutes to complete, no tools required. Additionally, the drive hub is fitted with a set screw that can be moved into one of three different holes to provide additional lift from the cam, resulting in increased efficiency of the cam. This provides the drummer with the ability to fine tune where in the beater return arc the footboard and beater get an extra instantaneous lift. The drive cam can also be used with the additional lift feature removed. Adjusting the cam lift feature requires a hex wrench which is provided. The beater and footboard angles are adjustable independently of each other without the need for tools or drum keys. The chain drive mechanism can easily be replaced with a strap drive that is included with every pedal. Each footboard is fitted with removable nylon set screws that provide the ability to fine tune the amount of slip/grip your foot experiences on the footboard. These set screws can be totally removed to provide a smooth footboard surface as well. Each pedal includes a bass drum clamp mechanism that is completely actuated from the topside of the pedal. The pedal can be attached and removed from the bass drum while the drummer is sitting on the drum throne.

Return Force vs. Beater Travel

All Airlogic pedals come fitted with black, hard felt Danmar beaters that produce a full, resonant bass drum sound and include hardened beater shafts. The double pedal includes unique stainless steel universal joints that provide constant velocity rotation with zero backlash. These unique joints have proven to be far superior to the typical block and pin style universal joints found on most double pedals and can only be found on Airlogic pedals. The spreader bar between the primary and auxiliary pedal is adjustable without the need for a drum key or any other tools. The double pedals can be disconnected from each other and played as two single bass drum pedals. The spreader bar can be totally disconnected from each of the double pedals using a drum key for easy transportation of the pedals. Each pedal has a combination of rubber/cork and hook and loop material on the bottom of the pedal base. This combination of materials has proven to provide the required amount of friction to keep the pedals from sliding an any surface as well as not be too aggressive so that they are difficult to remove from carpeted surfaces. Adjustable spurs are also included on each pedal base if more grip is required. Every effort has been made to give the drummer the ability to adjust each pedal without the use of tools or drum keys. A provided hex key is required to change from a chain to a strap drive as well as when the cam lift assist set screw is removed or moved to a new position on the cam. The footboard slip/grip set screws can be removed/installed /adjusted with a straight blade screwdriver. All components of Airlogic pedals are CNC machined from 6061 aluminum, brass and stainless steel. There are no die cast parts on an Airlogic pedal.

Why Are Airlogic Pedals Different from Spring Pedals:

Airlogic pedals were not designed just to be different, they were designed to offer a drummer a new response and control not possible with a spring pedal. Airlogic pedals are different because they introduce a new technology to bass drum pedals that translates to a feel that is not possible with a conventional spring pedal. They offer a paradigm shift in the way drummers can interact with their bass drum. To a drummer, the snare drum is most likely the most personal component of the drum kit. We believe a close second to the snare drum is the bass drum pedal. The bass drum pedal is the only access a drummer has to his bass drum. A pedal that offers a more natural feel and response opens up different playing possibilities, helping the bass drum to become a more integrated component of the drum kit. Many of these possibilities do not require the drummer to change his foot technique to get the pedal to respond in the manner he is seeking.
