Custom-designed by Dave Friedman himself, the all-tube Synergy BE-DLX Preamp Module combines the iconic voicings of both the BE (Brown Eye) and HBE (Hairy Brown Eye) circuits into a single, highly flexible unit. Powered by two 12AX7 tubes, it features two identical channels equipped with independent Gain, Volume, 3-band EQ, a SAT (saturation) switch, and a BE/HBE toggle to smoothly shift between classic, responsive British crunch and high-gain drive. Deep tone shaping is available directly on the PCB, including a FAT switch for boosted low-end response, a Gain Structure switch to roll back gain for vintage textures, and a 3-position Cathode Select switch (preset to British voicing) to tailor input tube bass feel.

The Synergy Friedman BE, and HBE all-tube preamp modules were among Synergy’s most popular designs and for a good reason. They perfectly reproduce the tone and feel of Friedman’s legendary BE tube amplifiers, the standard by which all other modern, British-voiced amp heads are today judged.

Friedman is one of the most respected brands in tube amplifiers and thanks to Dave Friedman’s famed BE/HBE circuits, they’re as sought-after for their modern high-gain tones as they are for their classic roar.

Now, for the first time, with the BE-DLX you can get both the BE and HBE sounds from a single Synergy preamp module with more control than ever before.

DUAL CHANNEL ALL-TUBE

Like all Synergy Friedman modules, the BE-DLX was designed by Dave Friedman himself. Both all-tube channels are identical recreations of the BE tube preamp but feature a full, independent suite of controls, including volume, gain, and a 3-band EQ per channel for added flexibility. Their BE/HBE mini toggles takes you from responsive, bluesy crunch to the high gain used by today’s most respected rock and metal guitarists. Set one channel to a vintage rock crunch and the other to an HBE-powered modern metal tone. Or switch between a rhythm and boosted lead sound.

The BE-DLX module features two circuit board mounted switches. A two position FAT switch lets you add overall low-end response. The Gain Structure switch lets you reduce the gain of the module for a classic vintage tone.

The Synergy BE DLX module is like having two legendary Friedman amplifiers in one compact, all-tube, and incredibly convenient package.

CATHODE SELECT FUNCTION:

The Friedman BE-DLX module features a patented 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 make up their input tube circuit. Synergy has 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). The SOLDANO / VAI module use position 3 (1.8K resistor and 1uf capacitor). Of course, you can experiment and try any of the positions to see what you prefer. The BE-DLX is present to the center position 2 (2.7K resistor and .68uf capacitor).

Synergy hardware and interchangeable preamps are protected under US patent.
