The responsive material provides a distinctly different playing feel from conventional wooden drumsticks and is particularly well suited to cajon playing. The durable polypropylene fibres flex under powerful accents and edge strokes. This allows the Poly Brush XL to combine excellent resistance and durability with a controlled playing feel at more restrained dynamic levels. Two adjustable rubber rings allow the bundle of polymer fibres, and therefore the sound, to be modified as required. The rubber-covered grip provides secure handling. At 365 mm long and 26 mm in diameter, the XL version offers a substantial design for versatile percussion applications.", "additional_text": "Model: Poly Brush XL \n Instrument type: Percussion brush \n Bristle material: PP polypropylene \n Flexible polymer fibres \n Grip: Rubber \n Weight: Heavy \n Two adjustable rubber rings \n Adjustable sound \n Durable and resilient construction \n Flexible material yields under powerful accents \n Particularly suitable for cajon \n Length: 365 mm \n Diameter: 26 mm \n Manufacturer: Rohema Percussion OHG", "sku": "61296", "mpn": "61296", "ean13": "", "upc": "", "brand": { "@type": "Brand", "name": "Rohema Percussion OHG", "url": "https:\/\/musiccraft-instruments.com\/en\/rohema-percussion-ohg_11" }, "manufacturer": { "@type": "Organization", "id_manufacturer": 11, "name": "Rohema Percussion OHG", "url": "https:\/\/musiccraft-instruments.com\/en\/rohema-percussion-ohg_11" }, "supplier": { "@type": "Organization", "id_supplier": 1, "name": "Migma e.G." }, "main_category": { "id_category": 89, "name": "Brushes", "link_rewrite": "brushes", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/en\/mcc\/mcc_agent\/category?id_category=89&setCountry=1&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/en\/brushes-89" } }, "categories": [ { "id_category": 4, "name": "Instruments", "link_rewrite": "instruments", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/en\/mcc\/mcc_agent\/category?id_category=4&setCountry=1&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/en\/instruments-4" } }, { "id_category": 6, "name": "Equipment & Essentials", "link_rewrite": "equipment-essentials", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/en\/mcc\/mcc_agent\/category?id_category=6&setCountry=1&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/en\/equipment-essentials-6" } }, { "id_category": 7, "name": "Restoration", "link_rewrite": "restoration", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/en\/mcc\/mcc_agent\/category?id_category=7&setCountry=1&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/en\/restoration-7" } }, { "id_category": 5, "name": "Highlight", "link_rewrite": "highlight", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/en\/mcc\/mcc_agent\/category?id_category=5&setCountry=1&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/en\/highlight-5" } } ], "features": [ { "id_feature": 1, "id_feature_value": 3, "name": "Product declaration", "value": "Single item" }, { "id_feature": 15, "id_feature_value": 130, "name": "Taxation", "value": "Standard Rate" }, { "id_feature": 9, "id_feature_value": 446, "name": "Instrument", "value": "Brushes" }, { "id_feature": 9, "id_feature_value": 451, "name": "Instrument", "value": "Cajon" }, { "id_feature": 22, "id_feature_value": 171, "name": "Intended Use", "value": "Beginner" }, { "id_feature": 22, "id_feature_value": 172, "name": "Intended Use", "value": "Intermediate" }, { "id_feature": 18, "id_feature_value": 445, "name": "Core material", "value": "Polymer fiber" }, { "id_feature": 18, "id_feature_value": 375, "name": "Core material", "value": "Rubber" } ], "agent_faqs": [ ], "images": [ { "id_image": 2987, "cover": true, "position": 1, "legend": "Rohema Poly Brush XL \u2013 Heavy-Duty Percussion Brush with Polymer Fibres", "url": "https:\/\/cdn3.musiccraft-instruments.com\/2987-large_default\/rohema-poly-brush-xl-cajon-brush.webp" } ], "shipping_weight": { "@type": "QuantitativeValue", "value": 0.5, "unitCode": "KGM", "note": "Shipping weight, not product content." }, "variant_model": { "has_variants": false, "variant_count": 0, "default_id_product_attribute": 0 }, "offers": { "@type": "Offer", "offer_scope": "product", "id_product": 510, "id_product_attribute": 0, "url": "https:\/\/musiccraft-instruments.com\/en\/p\/rohema-poly-brush-xl-cajon-brush-510.html", "price": 26.90, "priceCurrency": "EUR", "availability": "https://schema.org/InStock", "itemCondition": "https://schema.org/NewCondition", "seller": { "@type": "Organization", "name": "musiccraft -
