For fun I thought I would start an appreciation thread for one of my favorite builders of all time, MJM Guitar FX. His London Fuzz has always been at the top of the list for a Fuzz Face aficionado like myself. I've taken some screenshots from basic image searches to create a small timeline of the London Fuzz and depict its inception to what it currently is now. A bit archaic in some regards to early build quality, but I find that part of the charm with these. BUT NEVER DOUBT THE TONE! Folks have always considered the "early big boxes" the most sought after which stands to reason. But honestly, there's not a huge margin of difference between those and later examples. There's plenty more photos across the internet, but it appears the same electrolytics, resistors, and even the transistors have remained the same quality or brand for the most part throughout the years (with some NOS sprinkled in sparingly). There was a formula and consistency to the madness, you can't go wrong with any of them in my experience whether it be early or later models. I've owned both with no complaints! The two with the green-pcb's pictured below are mine, germanium and silicon! These white-box versions are no longer in production sadly but are highly recommended. I've had the early big boxes but have equally settled on these white-box ones!
