Synergy Modules | Friedman HBE Preamp

The Synergy FRIEDMAN HBE Preamp Module offers guitarists the acclaimed high-gain tones of Dave Friedman's BE-100 amplifier in a convenient module format. Dave Friedman has a long-standing reputation for crafting exceptional rock 'n' roll tones, with over 25 years of experience modifying, repairing, and building amplifiers for renowned musicians such as Jerry Cantrell and Steve Stevens. His expertise led him to establish his own line of high-quality guitar amplifiers, instruments, and effects, gaining a significant following amongst professional players.

Friedman amplifiers, including models like the BE-100, Buxom Beauty, and Butterslax, are recognised for their distinct sonic characteristics and are increasingly becoming the preferred choice for rock guitarists. The BE-100, in particular, is highly regarded for its ability to deliver powerful overdriven tones while retaining the individual nuances of a player's style. Its HBE boost circuit is a favoured feature, allowing players to switch from hard rock rhythm tones to high-gain lead sounds without sacrificing clarity and tight low-end response.

The Synergy FRIEDMAN HBE preamp module brings the specific tone and feel of the BE-100's boosted HBE channel directly to Synergy amplifier rigs. Designed by Dave Friedman himself, this module accurately captures the sonic details and touch sensitivity of his flagship amplifier, avoiding mere modelling or emulation. The HBE module is powered by two 12AX7 preamp tubes and features two channels. This allows for seamless switching between a high-gain rhythm sound and a boosted lead tone, or provides two channels of aggressive, present, and harmonically rich overdrive.

The module is equipped with two channels, each featuring individual gain and volume controls, along with a shared three-band EQ for tonal shaping. A notable feature is the Cathode Select Switch, a three-position switch that allows users to adjust the input tube's bass response to emulate the original circuitry of different amplifier designs. This affects the overall feel and tightness of the sound. The switch offers three popular component combinations, with the Friedman modules, including the HBE, preset to position 2, which uses a 2.7K resistor and a .68uf capacitor. This feature provides users with the flexibility to experiment with different input stage characteristics to find their preferred sound. For Synergy rig owners seeking a top-tier high-gain British tone with an added boost capability, the Synergy FRIEDMAN HBE Preamp Module is a valuable addition.
