Bubblesound LP40: The Standard in Analog Warmth The LP40 is a discrete 4-pole low-pass VCF that captures the quintessential sound of vintage subtractive synthesis. Known for its sm ooth frequency response and "rubbery" resonance, this transistor ladder filter is the ideal tool for taming aggressive waveforms or adding weight to bass patches. Because it is a discrete design, it saturates beautifully when hit with high-gain signals, adding a layer of harmonic complexity that integrated circuits simply cannot match. With its high-contrast black panel, the LP40 is as much a visual centerpiece as it is a sonic one. Key Features: Discrete Transistor Ladder: High-fidelity analog path for a timeless, warm sound. Harmonic Input Drive: Naturally compresses and saturates signals for a "thicker" tone. Liquid Resonance: A musical resonance profile that can be used for "pings" or as a sine-wave oscillator. Dual Modulation Inputs: Includes dedicated CV inputs for complex, evolving cutoff movement. Sleek Black Aesthetic: Professional-grade black-anodized finish for a cohesive rack look. Technical Specifications: Width: 8HP. Depth: 25mm (Skiff friendly). Filter Slope: 24dB/octave. Current Draw: +20mA (+12V), -20mA (-12V). Show more
