ES04 - VCM 1 Full Kit

The simplest of the Serge Wave Multipliers with switchable effects.

This DIY synth is a full kit in the Eurorack format.

Availability: In stock




The ES04 is the simplest of the three Voltage Controlled Multipliers (VCM), but it has two switchable effects.

The overdrive section from the VCM which has two switchable effects.

With the switch set at the "OVERDRIVE" position, the module functions to "square-up" an incoming signal. This is not the same as a simple comparator squaring function, though, since there is a rounded flattening of the signal peaks: an effect somewhat similar to overdriving a tube amplifier (except that in this version the process is voltage controllable!).

With the switch in the "LINEAR VCA" position, the module is a linear gain controlled VCA. This is useful for various functions such as amplitude modulation and for gating signals into the other sections.
