INVENTORY #58452

BRAND: STG Soundlabs

MODEL: Sea Devils Filter

FUNCTION: Eurorack Synthesizer Module

PRODUCT DESCRIPTION: This listing is for an STG Soundlabs Sea Devils Filter Eurorack Synthesizer Module. The STG Soundlabs Sea Devils Filter is a 3-pole diode ladder low-pass filter for Eurorack systems, designed as a faithful recreation of the filter found in the British EMS VCS3 (Synthi) suitcase synthesizer. It is known for its distinct 18dB/octave slope and aggressive, "bubbly" resonance that can reach full self-oscillation.

SPECS:

• EMS Heritage: The circuit is modeled after the diode ladder design of 1970s EMS products, providing a "creamy" and "smooth" sound that differs significantly from standard Moog-style transistor ladders.
• Voltage Controlled Resonance: Unlike some vintage clones, this module offers full voltage control over the resonance (labeled "Response"), allowing for dynamic, modulated feedback effects.
• Input Modulation: It includes two frequency CV inputs and an "Amount" knob that is also voltage-controllable, which adjusts the intensity of the incoming modulation signal.
• Build Quality: Reviewers on Mod Wiggler and Astro Chicken praise the large, sturdy knobs and firm action, noting it as a high-quality "modern classic".
• Width: 14 HP.
• Depth: 97 mm (approximately 3.75 inches). While older versions were deeper, newer production runs are described as more "skiff-friendly".
• Current Draw: 30 mA on the +12V rail and 30 mA on the -12V rail.
• Circuitry: Features a PCB designed by Detachment 3 Engineering (Yves Usson).

ACCESSORIES INCLUDED: 

• 16 Pin Eurorack Power Cable
• (4) Eurorack Screws & Washers
