Historical Context and Positioning in the Range
This head fits within the logic of modern heads featuring external sustain control via the EMAD system. The principle: preserve the natural character of the bass drum while offering immediate damping adjustment, without internal modifications or permanent changes.
Target Audience for This Drum/Instrument
It is particularly suitable for intermediate to advanced drummers seeking a bass drum that cuts through the mix, with present lows and a clear attack. Perfect for Rock and Fusion, it remains highly relevant in Jazz if you prioritize warm lows and controlled sustain depending on the chosen muffler.
Features and Innovations
The G-Plus technology combined with the EMAD system allows switching from an aggressive, precise sound to a more diffuse response in seconds, simply by changing the external muffler (13 mm for more openness, 18 mm for greater control). The transparent finish promotes a direct response and a clear playing feel.
Sound
With its single 12 mil ply, this head emphasizes a bass-heavy attack and excellent stick definition. The damping system modulates sustain: more open for a breathing low end, or tighter for a short, precise bass drum sound that is very effective in close miking situations.
