Review BUBBLESOUND High Pass Filter Modular Eurorack Demo Perfect Circuit

The Bubblesound HP40 High Pass Filter is a versatile and high-performing module for your Eurorack modular synthesizer system. This filter, designed and manufactured by Bubblesound, is a part of their Demo Circuit series, which offers a wide range of functionality in a compact package.

The HP40 High Pass Filter is a four-pole, transistor ladder design, providing a smooth and natural sounding filter response. It offers a frequency range that can be adjusted from below 20Hz up to 16kHz. With its unique design, this filter is capable of producing a wide range of sounds, from subtle low-pass filtering to deep, resonant high-pass filtering.

The HP40 High Pass Filter module features a frequency control input, which allows you to manually set the cutoff frequency using an attenuverter. Additionally, it comes equipped with a CV input, enabling you to control the cutoff frequency using an external voltage source. A dedicated resonance control knob allows you to add self-oscillation to the filter, creating complex and intriguing sounds.

The HP40 also includes a polarity switch, which inverts the signal polarity before it passes through the filter. This can be useful for creating certain effects or for dealing with signal phase issues. Furthermore, a dedicated bypass switch is included, allowing you to easily bypass the filter and pass the raw signal through the module.

The HP40 High Pass Filter is built with the highest quality components and is meticulously hand-wired, ensuring a reliable and stable performance. The front panel is made of high-quality aluminum, providing a sleek and durable finish. The module measures 12 HP (Height Units) and requires a 12V and -12V power supply to operate.

In summary, the Bubblesound HP40 High Pass Filter is a powerful and flexible addition to any Eurorack modular synthesizer system. Its smooth and natural sounding response, coupled with its extensive control options, make it an essential tool for creating intricate and expressive electronic music and sound design.
