With the Synergy Diezel VH4 Preamp Module you have access to the same searing guitar tones that have made the Diezel brand one of the most respected names in the amplification industry. But this is no mere emulation. Peter Diezel personally designed the module, ensuring your tone sings with the authentic grind and character of its namesake amplifier. This two channel design boasts independent 3-band EQ sections on each side, allowing you to fine tune separate lead and rhythm tones. Once you put the Synergy Diezel VH4 Preamp Module to work, its glowing set of 12AX7 preamp tubes will rip through your speakers with the savage refinement that only a Diezel can offer.
The Synergy VH-4 pre-amp modules features two channels with a gain, volume and three band EQ.
The VH4 modules features a 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 makes up their input tube circuit. We have selected the three most popular combinations which you can access with this switch. The modules will come preset to Peter Diezel’s preferred setting which for the VH4 module is position 2 (2.7K resistor and .68uf capacitor).
