Fargen Micro Plex Full Stack

Fargen · amplifier

The Fargen Micro Plex Full Stack is a 5-watt Class A boutique guitar amplifier head from Fargen Amplification, paired with a miniature full-stack cabinet configuration. The Micro Plex uses a single 6L6 (octal tube swappable to 6V6 or 6550), a 12AX7 preamp tube, and push-pull Gain Boost and Tone Shift controls. Hand-wired with carbon composite resistors, SoZo mustard caps, and US-built transformers, it delivers vintage Class A clean-to-crunch tones from Hendrix-era clean to classic rock saturation at recording volumes.
