Data sheet

The wood used in the manufacture of percussion instruments varies according to the area of origin; In Latin America, the variety of trees is enormous, in North America the maple is the most sought after and in Europe beech and birch have always been used to build percussions in general. Fortunately, the birch has the right characteristics for the drawer, since it offers a very sharp and clear sound. And as for battery drums, plywood is often used to make drawers.

Most of the DG drawers are made of birch. The different parts are combined with ultra-resistant vinyl glues, and varnished with a double layer of polyurethane product.

Reduced Size Tapa – RST

The concept of the Reduced Tapa Size (RTS) comes as a natural development of the patented DG drawer, and consists essentially of making each knocker lid of the drawer slightly smaller than the body of the instrument itself. The majority of drawers in the market have a cover built to exact measure of the drawer, milled, sanded and varnished on the body of the instrument, which makes it impossible to replace a hitting cap, without having to re-sanding and varnishing again all the drawer completely.

This complete fusion between the two parties can become a problem over time, because the two things have different useful vitas, being that of a hitting cap much shorter, being the thinnest, and the one that is hit.

For this reason we proposed to allow the end user the possibility of changing the knocker lid, as well as how a drummer can change the patches of his drums.

The subject has a classification question in the background: does the cajón belong to the idiophone category, like maracas, or rather to that of a membranophone, such as tumbadoras?

The second one seems more appropriate to us, and that is why we manufacture all our covers after cutting them with digitized numerical control machines, so that they are all perfectly equal and interchangeable.

The countersunk holes correspond exactly to all the covers.

The perimeter of the lid is rounded, and is coupled to the edge, also rounded, of the body of the drawer, leaving a “soft jump” between the two surfaces, little detectable to the eye and touch.

In this way it is possible to replace a lid, without having to go through a workshop.

A practical solution, which in addition to considerably lengthen the life of the instrument, allows to change one type of material for another, use different finishes, in short to have more options.

Removable Snare System – RSS

The Removable Snare System (RSS in English), is another original feature of the DG models, developed from the patented model Zambo, in which the snare was removable from the body of the drawer.

From the beginning of our activity it seemed to us that the possibility of removing the straps without having to dismantle the whole drawer was a fundamental quality, in order to keep the sound of the drawer with its spark.

Each stroke in the drawer is a blow to the snare, which in the majority of cases are made up of guitar strings.

The break is an event more than likely, something that can happen, of course, also depending on the use made of the instrument.

The more intensive, the greater the chance of breaking.

There are alternatives to guitar strings, such as drum box beats or very thin springs, but the acute effect is not the same, nor the effectiveness and precision in the application of tension, roughly speaking, “tuning” .

Our system allows the replacement of the ropes in a few minutes, and without having to disassemble the drawer.

The strings are mounted on wooden blocks, one is fixed at the top of the drawer, visible externally but bolted internally with a pigeon nut, while the other block is located at the bottom, with the function of tensioner.

The tensioner is adjusted with an Allen key through a screw, whose head is on the lower external side.

To remove the blocks then, you only need to unscrew the inner pigeon nut from the top, and unscrew completely from the bottom.
