Key Features
The Synergy OS 2-Channel Preamp Module is ideal for players drawn to the expressive feel and mid-focused clarity associated with the famed Overdrive Special. This module captures the delicate response that highlights every nuance of a player's technique, then shifts smoothly into the saturated sustain that made the original amplifier so sought after.
Product Ref: 355031
The OS module focuses on the qualities that made the original Overdrive Special so respected. The clean channel provides a mid-forward voice that brings out subtle nuances in picking, phrasing and dynamics.
Switching to the overdrive channel introduces the smooth and vocal sustain associated with many iconic recordings. Both voices work together to showcase playing detail, making the module suitable for styles that rely on touch sensitivity. The transition between clean clarity and focused drive remains natural and musical, keeping the core characteristics intact.
Bright and Deep switches offer quick shifts in top-end sparkle and low-end weight. The Rock/Jazz switch changes the overall character of the module, allowing movement between a fuller, more aggressive sound and a smoother response that suits cleaner passages.
These controls sit alongside a traditional three-band EQ and a presence control that fine-tunes upper-frequency definition in overdrive mode. This structure keeps tone shaping accessible without requiring deep menu diving or complex routing.
The three-way cathode select switch adjusts the bass behaviour and feel of the input stage. Each setting changes how the preamp responds to picking attack and cabinet pairing. This feature makes the module adaptable across different setups, offering firmer or looser low-end response based on preference. It also helps the OS module retain consistency across a variety of playing volumes, which is useful when switching between rehearsal spaces and larger stages.
Two 12AX7 valves supply the harmonic complexity associated with classic tube circuits. Controls for Bass, Mid, Treble, OD Level, OD Ratio, Presence, Master and Volume are arranged in a clear layout that mirrors the feel of the original design while remaining easy to navigate.
The interchangeable Synergy format simplifies installation and integrates the OS module seamlessly with other Synergy components. Compact dimensions and light weight make it a practical choice for players building versatile rigs that still rely on authentic valve response.
