This device boasts a genuine analog sound processing system meticulously designed with premium-grade military NOS Soviet vacuum tubes, low noise FET-input Burr-BrownTM opamps, hand matched inductors, capacitors and in-house manufactured Bettermaker TT-1 audio transformers. All designed, developed and built by the talented Bettermaker team in Poland.

The transformers represent the closest substitute to renowned vintage models, ensuring a distinguished auditory experience characterized by minimal harmonic distortion, particularly in the lower frequency range. For those seeking an enhanced warmth in sound, we recommend activating the “HEAT” mode.


Bettermaker Valve Stereo Passive Equalizer is delivered with hybrid DAW plugin that allows you to control and recall all settings of the hardware (including HEAT on/off). Additionally provides high quality digital HPF and LPF (works as regular AU/VST3/AAX plugin), spectrum analyzer, presets and session snapshots.

Connection with the hardware unlocks some extra functionality: dual mono operation, audio level metering, quantize (step) mode for all physical knobs and Auto Audition function – currently selected band will be soloed to let you hear the changes.

You can also adjust VSPE filters’ gain and frequency by dragging handles on the EQ curve graph.

Please note that dual mono operation is available only when DAW plugin is connected and active. In standalone mode VSPE will link both channels and disable quantize mode.

HEAT function is always linked, regardless the link mode or channel selected.
