Synergy OS 2ch Tube Pre-Amp Module

INTERCHANGEABLE PRE-AMP
Across the front panel, the OS features the same basic controls as the Overdrive Special amplifier. Dual footswitchable channels enable switching between the unique Dumble clean with its mid-forward clarity to the fabled smooth, singing sustain that gives the Overdrive Special its name. You’ll also find Bright and Deep, along with and Rock/Jazz switches that – along with a 3-band EQ – tailor your tone while always retaining the Dumble character. Finally, a master presence control adds just the right amount of clarity to the preamp module’s OD mode.

There’s nothing that sounds or feels exactly like a Dumble. But with the Synergy OS preamp module, you can possess the essence of one of the finest amps in the world alongside all of the other classic tones available from the Synergy system.

CATHODE SELECT SWITCH:
This three-position switch allows you to configure the input tube bass response to match the original circuit of the selected module. This will affect the feel and tightness. Each amp designer has a specific combination of components that make up their input tube circuit. We have selected the three most popular combinations which you can access with this switch. You can experiment and try any of the positions to see what you prefer.

Synergy hardware and interchangeable pre-amps are protected under US patent.
