1989 THD – Plexi Head – ID 5447

Rare and sought-after THD Plexi Head from the early years of the US boutique company (founded in 1987).
This model pays homage to the great Marshall amps of the 60s - puristic and with an authentic vintage character.

The power amplifier works with 2x 6L6 tubes and therefore delivers a slightly rounder, warmer sound than the typical EL34-based Plexis - ideal for classic rock, blues and harder rock...
Two separate channels (Bright / Normal) can be operated individually or bridged, which enables enormous sound diversity.

The tweed-finish housing underlines the boutique character of this exceptional amp.
A real collector's item, rare and hard to find, and at the same time a fantastic player amp with an honest, direct sound.
