Mooer M012 Micro PreAMP Based on Friedman The Brown Eye 100A modern, hot rodded take on a classic British Plexi. Modelled from a 100Watt tube amp designed by a legendary American amp builder, US GOLD 100 is essentially the British Style amp that everybody wants to own. With its big, tight low end and harmonically rich and detailed voicing, this preamp remains dynamic and clear even at high gain settings. The clean channel goes from blues to classic rock and the drive channel goes from hard rock to metal.
