Advanced spring reverb preamplification

The core of the Spring Amp III lies in its specialised reverb preamplifier design. Using a discrete transistor front-end, the amplifier ensures an ultra-low noise figure and pristine sound capture from your reverb tank. It is paired with a robust 7.5W constant current amplifier optimised for 8-ohm input tanks, pushing the springs to their full potential with extended treble response and impressive output volume. This setup delivers dynamic, clear, and highly musical spring reverb tones that retain the organic texture and lively character that define classic dub and experimental sounds.

Built-in filter with crossfader control

The inbuilt analog filter offers extensive tonal shaping options with a 12dB per octave slope. Featuring a continuous crossfade between high-pass and low-pass outputs, the filter provides rich modulation opportunities. You can easily sweep from bright, piercing highs to deep, resonant lows, sculpting the reverb’s decay and character in real time. A routing switch allows you to decide if the filter processes the sound before or after the spring tank, offering two distinct tonal approaches: mellow and harmonically rich or dramatic and splashy.

Soft clip saturation for warm analog tone

Spring Amp III features an integrated soft clipper on both the input and filter stages. This addition means you can push signals into gentle saturation without unwanted distortion artifacts or damaging your speakers. The resulting sound is thick, warm, and full of harmonic complexity, adding an expressive edge to your dub swells, rhythmic hits, and ambient washes. The soft clipping works seamlessly across the unit's dynamic range, making it highly playable for hands-on performance techniques.

Independent filter and preamp controls

Independent volume controls for both the preamplifier and the filter sections grant significant flexibility. This configuration allows the Spring Amp III to be used not only as a spring reverb driver but also as a standalone analog filter unit, ideal for creative signal processing or live improvisation. Connect it directly after an instrument, a mixer, or a studio interface to add lush filtering and saturation to any sound source, expanding its usability well beyond traditional spring reverb applications.

A legacy of passion and refinement

The Spring Amp III represents years of passion and continuous improvement from Benidub, refined through hands-on experience and invaluable user feedback. It carries forward the spirit of classic dub effects while pushing forward into new creative possibilities. With its intuitive layout, top-tier audio fidelity, and inspiring hands-on controls, the Spring Amp III is not just another reverb accessory – it is a performance instrument in its own right, designed for artists who want their effects to be as dynamic and alive as their music.
