Synergy DRECT All-Tube 2-Channel Rectifier-Style Tube Guitar Preamp Module


Manufacturer's Description

The Synergy DRECT is an all-tube, two channel module that pays homage to the legendary rectified amplifiers that have left an indelible mark on heavy rock for over three decades. In 1992, the 100-watt, 2-channel dual rectifier amp emerged, redefining the landscape and sound of heavy rock. Little did anyone know that its low-mid punch and searing gain would become the sonic foundation for countless bands seeking to amplify down-tuned aggression. Despite the various revisions, the Rev C is what introduced the amp to the world. Its Orange channel’s crunch and the Red channel’s high-gain prowess defined the unmistakable tone of rock and metal guitar, a legacy that lives on till today.


The Synergy DRECT module meticulously captures the game-changing character of this Rev C amplifier by faithfully reproducing the signature girth and articulation that’s graced numerous hard rock and metal classics. Adding even more flexibility than the original amp, this module allows you to set each channel to be either Orange or Red. For those craving the powerful tones of Metallica, 311, Linkin Park, Korn, Soundgarden and many more, the Synergy DRECT preamp module is your gateway to that iconic rectified sound.


The DRECT module features a three-position switch on the PCB which 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 makes up their input tube circuit. We have selected the three most popular combinations which you can access with this switch. The USA voiced modules typically use setting 1 (1.5K resistor and 22uf capacitor). British style modules use position 2 (2.7K resistor and .68uf capacitor) and modules like the SOLDANO and VAI modules are set to position 3. Of course, you can experiment and try any of the positions to see what you prefer. The modules will come preset to the preferred setting which for the DRECT module is position 3 (1.8K resistor and 1uf capacitor).


The DRECT module features a secondary switch allowing the new Synergy modules to be used in older single channel Egnater and Randall modular amps/preamps that do not accept the dual channel modules. This allows access to either of the module channels when that slot is turned on. You will still not be able to switch between the two channels due to the limitations of the older hardware. You can set it so either module channel one or module channel two will turn on when the slot is selected. Set to Dual when using the module in units that have the switching circuit to access both modules. If you are using a single channel only amp/preamp, setting to DUAL will make the bottom module channel active. Set to Single will cause the top channel of the module to come on when selected.
