The Shadow Hills Industries Mono GAMA is the 500 Series version of the acclaimed Golden Age Microphone Amp, an all-discrete pre with transformer switching matrix, meaning you can change the personality of the Mono GAMA instantly to perfectly suit whatever you're recording. Go between two different colors with the Nickel and Steel trannies, or flip over to the Discrete setting to take the output transformer out of the equation entirely for lightning-fast transients and ruler-flat response.
