Keeley doesn't perform mods anymore and BD-2s with legit Keeley mods are going for crazy money at the moment. The Super AT Mod is taking aim at that while adding something different to the mix. Robert and Andy worked on this together and as the name implies, it NAILS tones from the original Keeley BD-2 PHAT Mod but then AT Mode tightens low end and focuses low-mids for lead work. Keeley knew it was good when it replaced Andy's legit Keeley modded BD-2. Actually, there's two Super AT Mods on his board, one for each mode... it's that good.
