These devices meant for home studios eventually found their way onto hit records like Springsteen’s Nebraska, the Wu-Tang Clan’s Enter the Wu-Tang, and Spoon’s Gimme Fiction. Many of the vocal parts and fuzzy guitar tracks on Gimme Fiction – a huge inspiration for the creation of the Colour Box – were actually recorded on a vintage multi-track unit. Since hearing those recordings, the 424 Gain Stage has been brewing in the background, and now we’re proud to bring it to you.\nIn this historically accurate recreation, we perfectly replicated the original 424 MKI circuit using the original UPC4570 and NJM4565 op-amps and all the original controls, which is crucial for recreating the unique character that makes the old units sound so good.  The 424 MKI's gain controls–trim, channel volume, & master volume–all work in tandem for dialing up your desired tone and can be further refined with the Low and High EQ settings. In addition, our unit offers a ¼” output alongside a balanced XLR output (DI out) for ultimate flexibility in any situation, live or studio.\nThe 424 Gain Stage as a DI\nGoing DI will give you the exact same unparalleled gooey texture and lo-fi fuzz you get when plugging directly into a 424 without the hassle of dragging around your beloved vintage unit. Leave it on your recording desk for easy access. If you want to get fancy,  you can toss an Active A/B/Y switcher at the end of your rig and send the A output to your amp and the B outpu","images":["https://cdn.shopify.com/s/files/1/0610/7122/9028/files/424Update.png?v=1765894243","https://cdn.shopify.com/s/files/1/0610/7122/9028/files/424Update_QR.png?v=1765894243","https://cdn.shopify.com/s/files/1/0610/7122/9028/files/424Update_QL.png?v=1765894243","https://cdn.shopify.com/s/files/1/0610/7122/9028/files/424-TopDown-2-Edit.png?v=1765894243","https://cdn.shopify.com/s/files/1/0610/7122/9028/files/424-Vert2-Edit.jpg?v=1765894243","https://cdn.shopify.com/s/files/1/0610/7122/9028/files/424-TopDown-3-Edit.jpg?v=1765894243"],"price":249,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:09.205Z"},"share_url":"https://firestarter.network/l/lst_MNG_SIvp","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
