Review ADDAC SYSTEM Gotharmans Vc Tube Filter Eurorack Demo Perfect Circuit

The ADDAC SYSTEMS ADDAC611 GoTHARMONIC VC Tube Filter is a versatile and expressive Eurorack module that brings the warm, analog character of vacuum tube circuitry to your modular system. This filter offers voltage controlled frequency and resonance, allowing for a wide range of timbral possibilities, from subtle filtering to complex and resonant sweeps.

At its core is a hand-selected, high-quality NOS (New Old Stock) 12AX7 dual triode tube. The tube is encapsulated in a protective cage to ensure longevity and reduce the risk of tube microphonics. The tube's characteristic warmth and subtle harmonic distortion are then shaped by a meticulously designed analog circuit.

The ADDAC611's frequency control is voltage controllable, with a range of approximately 20 Hz to 20 kHz. The resonance control, also voltage controllable, can self-oscillate when set to high values, transforming the module into a versatile voltage-controlled oscillator. The filter can be operated in both low-pass and high-pass modes, providing even more sonic variety.

The module's front panel features an attractive, hand-brushed aluminum faceplate, with clear, easy-to-read labeling, and robust, durable knobs. The filter's input and output jacks are located on the right side of the module, and a small switch on the left side allows for easy selection between low-pass and high-pass modes.

The ADDAC611 GoTHARMONIC VC Tube Filter is not just a simple filter it's a creative tool that adds character and warmth to your modular system. The interaction between the voltage-controlled parameters and the tube circuitry results in a unique and expressive sound that sets it apart from digital filters. Whether you're looking to add depth to your basslines, create complex textures, or design intricate filter sweeps, the ADDAC611 GoTHARMONIC VC Tube Filter is an essential addition to your Eurorack setup.

The Addac System Addac611 Gotharman VC Tube Filter is a eurorack module that offers voltage controlled filtering with tube overdrive and distortion capabilities. Here are some pros and cons that might help you make an informed decision about purchasing this module:

1. Unique sound: The tube filter section provides a warm and organic sound that sets it apart from typical digital filters.

2. Versatile: The module offers both low-pass and high-pass filtering, as well as a band-pass mode. The tubes can be used for overdrive or distortion, adding additional character to the sound.

3. Voltage controlled: The filter cutoff and resonance can be controlled via CV inputs, making it a useful tool in a modular synthesis setup.

4. Build quality: Addac Systems is known for its high-quality builds, and the Addac611 is no exception.

1. Size: The module is relatively large, measuring 26HP, which might be a consideration for those with limited space in their eurorack case.

2. Power consumption: The module consumes a fair amount of power, drawing 135mA at 12V and 115mA at -12V.

3. Price: The Addac611 is a premium module, and its price tag reflects that.

In conclusion, the Addac System Addac611 Gotharman VC Tube Filter offers a unique and versatile sound that can add character to your modular synth setup. Its build quality is excellent, and its voltage controlled capabilities make it a useful tool in the studio or on stage. However, its size, power consumption, and price tag are considerations that should be taken into account.

If you have the space, power, and budget for this module, it can be a valuable addition to your modular setup. However, if these factors are a concern, there are other, more affordable and compact filter options available on the market. Ultimately, the decision to purchase the Addac611 depends on your individual needs and preferences.
