{"type":"firestarter.listing","listing":{"id":"lst_sTB9MoJ2","product_name":"Katzenkönig","category":"Effects","description":"\nWe combined the best elements of a Tone Bender MkII fuzz with a Rat distortion to create something that sings like a fuzz but is tight like a distortion.\nIt loves humbuckers and single coils. It loves your cranked amp and your super-clean amp. The front half of the circuit is based on the Tone Bender MKII, widely considered the most desirable of the Tone Benders. In the original, a germanium transistor makes the signal loud. A second transistor makes it very loud. A third one makes it ridiculously loud.\nThe filter control works wonders, enabling shades you'd never obtain from a Tone Bender MKII.","images":["https://cdn.shopify.com/s/files/1/0370/1873/0628/products/KATZ_SHOPIFY-01-min.png?v=1652346691"],"price":179.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:04.334Z"},"share_url":"https://firestarter.network/l/lst_sTB9MoJ2","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
