The SOS 59 ’Gold!’ pack contains a capture of the EarthQuaker Devices’ Acapulco Gold in each of the ToneX, NAM Standard and NAM Nano formats. Because the  pedal’s one knob is simply a master volume, in reality, it only has one sound (hence the 'single capture/free' approach) but what a sound that is!
 
EarthQuaker Devices desribe this unruly beast as, 'a dirt-simple distortion Device modeled after the sound of a cranked vintage Model T amplifier, bringing the openness, clarity, and crunch that only a dimed tube amp can provide, at a fraction of the size, and without expensive maintenance costs!
