Hey @Lytt Effects, I goofed and used On-On toggles so I don't have the "stock" setting. But as I recall down was Glass and Up was Fat. It's basically turned 90 degrees from the retail pedal.
You mean the Xotic EP Booster? I think you can get the EP Booster to sound close to the Clandestine with the internal dip switches. But by default it's more transparent than the Clandestine/Secret Preamp.
The 3 "EchoPlex" style boosters I've tried are the Clandestine (Secret Preamp), the AIONFx...
