This Atomica 100W was created in collaboration between Brad King and Mark Cameron, based on his designs. Although Cameron was initially expected to be directly involved, it became clear he couldn’t meet the production timeline, so the builds were handed off to respected names like George Metropoulos and Dave Friedman—who built this particular amp.
Often praised as the “perfect” modded Marshall, the Atomica is a design Cameron had been performing as a modification on Marshall circuits for years. Full ground-up Atomica builds from Cameron do exist, but they’re incredibly rare and routinely command five-figure prices. Many players believe that the Friedman-built examples hold their own against the originals without compromise.
One cool thing to note: ironically, Mark Cameron himself performed some additional (and undocumented) tweaks to this amp while the previous owner lived nearby. The amp remains in excellent condition with only light signs of use.
The user should note the "gain style" switch on the back has less dramatic changes the further clockwise you take it, for whatever reason.
