{"type":"firestarter.listing","listing":{"id":"lst_Bv5bUwcp","product_name":"Clean Little Secret","category":"Effects","description":"\n\nOur take on the low-gain Marshall sound is not to be taken lightly! Our Clean Little Secret is a low-gain platform that gets gritty in a hurry thanks to a refined approach to this foundational classic, with many of the original’s shortcomings addressed and improved upon.\n\nWe’ve conquered the high-gain Marshall amp-in-a-box some time ago, and now our Clean Little Secret takes the classic low-gain Marshall BB formula and gives it a much needed refinement. We’ve beefed up everything from the classic amp enhancer, from the tone stack to the output stage and more, giving you just the right amount of kick. A completely overhauled tone section gives you individual control over treble and bass bands as opposed to a global tone knob, and we’ve added some more bells and whistles to push the unity volume level up quite a bit. Our designer’s favorite op-amp keeps the action whistle-clean until you push the gain, giving you delicious edge-of-breakup tones at the end of the dial, but subdued always-on enhancement tones at any other position. Some secrets are better left unkept!","images":["https://cdn.shopify.com/s/files/1/0370/1873/0628/files/CLS-shop.png?v=1777623968"],"price":179.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:04.056Z"},"share_url":"https://firestarter.network/l/lst_Bv5bUwcp","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
