Fargen Amplification’s new Micro Plex is a hand-made, 5-watt Class A guitar amp with push/pull Gain and Tone Shift modes. Its circuit uses vintage-style mustard caps and carbon-comp resistors, U.S.-built transformers, and dual power-tube sockets to accept any octal tubes, in a cabinet that measures 16.5″ x 9″ x 7″.
