{"type":"firestarter.listing","listing":{"id":"lst_4lGAnLx8","product_name":"Knight School Distortion DIY Kit","category":"Effects","description":"We are offering these in DIY Kit form or fully assembled for you! Assembly is very straightforward and requires only a soldering iron, some solder, and proper ventilation; we’ll take care of the rest.\nThere is perhaps nothing more emblematic of modern guitar rock than the humble op-amp distortion. This effect took its greatest hold in the late ‘70s when Boss released the OD-1, but the concept of intentional hard-clipping distortion really took hold across three platforms that all released relatively close together: the ProCo RAT, the Boss DS-1 and the MXR Distortion +. The MXR unit is the simplest of the bunch, but unfortunately, we’ve found it a bit lacking. We’ve updated it to add an extra gain stage; the original utilized a single op-amp, but we felt that they left a little meat on the bone. We replaced it with a dual op-amp to goose the distortion and provide much more gain on tap than the average IC-based gain, giving tons of extra saturation with minimal-gain sparkle and clarity. An updated clipping diode arrangement provides maximum clipping without sounding harsh. Perhaps best of all, it takes other pedals extremely well without any offputting artifacts. You’re going to love this one.\n \n ","images":["https://cdn.shopify.com/s/files/1/0370/1873/0628/files/Ks-Distortion_shop.png?v=1762834018"],"price":84.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:04.113Z"},"share_url":"https://firestarter.network/l/lst_4lGAnLx8","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
