{"type":"firestarter.listing","listing":{"id":"lst_68wHtZXJ","product_name":"Fump Bridge-Side Dampener","category":"String Muters","description":"Palm-muted bass tone. Minus the palm.\nFree up your muting palm and discover a new path to the old school. The Fump is a simple muting device that slides over the strings against the bridge of your 4- or 5-string electric bass to instantly recreate that sweet staccato sound - without using your palm!The Fump was born as a natural step following the wild success of our FretWraps, and from numerous requests from players like you. If you've ever stuffed foam under the strings to try to achieve that coveted \"old school\" muted or upright tone, then you might give the Fump a try! While we definitely encourage mastering proper palm muting, the Fump simply opens up possibilities to discover new techniques and gives your hands the freedom to \"dig in.\"A few things to note:\n\nWorks best when string fingerboard setup has little to no radius\nTakes only a second to slide on or off, unlike the old cut foam solution\nClips onto your strap or music stand when not in use\nHas no moving parts\nCan be inserted from top or bottom\nRequires only a 1\" (2.5 cm) of space between pickup and bridge\n\n\n\n\n  \n    What is Fump?\n    \n      Fump is a bass string dampener that helps recreate the classic muted bass tones heard on countless vintage recordings.\n    \n  \n\n  \n    What kind of sound does it create?\n    \n      Think Motown, classic soul, vintage country, old-school rock, reggae, and jazz. Fump gives your bass a warm, punchy \"thump\" with a shorter note decay that sits beautifully in a mix.\n    \n  \n\n  \n    Why use Fump instead of palm muting?\n    \n      Palm muting sounds great, but it takes technique and consistency. Fump gives you that same vintage-inspired character instantly, so you can focus on playing instead of constantly managing your muting hand.\n    \n  \n\n  \n    What styles of music benefit most from Fump?\n    \n      Any song that calls for a tighter, more staccato bass sound. It's especially popular with players chasing vintage tones or looking for a more controlled low end.\n    \n  \n\n  \n  ","images":["https://cdn.shopify.com/s/files/1/0931/2816/products/FUMP5-BLK-b.png?v=1602824389","https://cdn.shopify.com/s/files/1/0931/2816/products/gruvgear-fump-12.jpg?v=1614763877","https://cdn.shopify.com/s/files/1/0931/2816/products/FUMP5-BLK-d.png?v=1614763877","https://cdn.shopify.com/s/files/1/0931/2816/products/gruvgear-fump-13.jpg?v=1614763877","https://cdn.shopify.com/s/files/1/0931/2816/products/FUMP5-BLK-a.png?v=1614763877","https://cdn.shopify.com/s/files/1/0931/2816/products/FUMP5-BLK-c.png?v=1614763877"],"price":19.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:23.336Z","product_rating":null,"product_rating_count":0,"seller_rating":null,"seller_rating_count":0,"units_sold":0,"reviews":{"count":0,"top":[]},"videos":[]},"share_url":"https://firestarter.network/l/lst_68wHtZXJ","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
