Description

Edit description

For guitarists who crave the legendary British high-gain sound, the Synergy Amps Marshall JCM 800 Preamp Module is a game-changer. Born from the iconic collaboration between Synergy and Marshall, this dual-channel tube preamp module encapsulates the essence of the JCM 800, revered by rock legends for its aggressive midrange punch and dynamic tonal range. The three 12AX7 tube architecture ensures that every note is delivered with the same harmonic richness and responsiveness that defined the hard rock and metal scenes of the '80s.

Each channel comes equipped with its own dedicated independent EQ controls, allowing players to craft distinct rhythm and lead tones without compromising on tonal integrity. The module also boasts a built-in 0-watt power amp and phase inverter, providing an authentic amp feel even at lower volumes. The Bright, High/Low input, and Cathode Select switches offer expanded tonal flexibility, enabling you to fine-tune your sound from a tight, aggressive attack to a smoother, warmer blend.

Designed to integrate seamlessly with Synergy host devices, the JCM 800 module is a must-have for any guitarist looking to expand their tonal palette while capturing the true Marshall spirit in a compact, modular format.

Key Features:

Dual-channel design with independent EQ and master volume controls
Three 12AX7 tubes with built-in 0-watt power amp and phase inverter
Authentic Marshall 2203/2204 circuit for legendary British high-gain tones
Bright switch and High/Low input toggle for enhanced tonal shaping
Cathode Select switch for adjusting tube reaction
Designed for compatibility with Synergy host devices like SYN-1, SYN-2, SYN-20IR, SYN-30, and SYN-50
Compact modular format for easy integration into existing rigs
