{"product_id":"evans-drumheads-hydraulic-bass-batter","title":"Hydraulic Bass Batter Drumhead","description":"EVANS Hydraulic bass drumheads give you the fat, deep, short sound pioneered by rock and roll drummers in the 1970s. Made with a thin layer of oil between two plies of 7 mil film (6.5mil \u0026amp; 7.5mil for Hydraulic Black), these heads not only suppress unwanted overtones, but are also famously easy to tune. Hydraulics have a defined attack, short sustain, and dark tonal character. This bass drumhead also features Level 360 Technology and is available in clear, red, blue, and black.","brand":"Evans Drumheads","offers":[{"title":"20\" \/ Blue","offer_id":43579482931265,"sku":"BD20HB","price":69.5,"currency_code":"EUR","in_stock":true},{"title":"20\" \/ Red","offer_id":43579482996801,"sku":"BD20HR","price":69.5,"currency_code":"EUR","in_stock":true},{"title":"22\" \/ Blue","offer_id":43579483062337,"sku":"BD22HB","price":73.0,"currency_code":"EUR","in_stock":true},{"title":"22\" \/ Red","offer_id":43579482964033,"sku":"BD22HR","price":73.5,"currency_code":"EUR","in_stock":true},{"title":"22\" \/ Black","offer_id":43579483029569,"sku":"BD22HBG","price":73.0,"currency_code":"EUR","in_stock":true},{"title":"22\" \/ Glass","offer_id":43579482898497,"sku":"BD22HG","price":73.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0669\/6042\/5025\/files\/ev_BD22HR_main_transparent.png?v=1773170425","url":"https:\/\/www.daddario.com\/en-fr\/products\/evans-drumheads-hydraulic-bass-batter","provider":"D'Addario","version":"1.0","type":"link"}
