PRODUCT DESCRIPTION
- Benidub Spring Amp III 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 mussical 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&rsquo
- 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 units 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 &ndash
- 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. TAD Type-4 Spring Reverb Tank Gives you the classic reverb character The TAD Type-4 delivers the sound made famous by vintage amplifiers. Its long chassis and four counter-wound springs produce a dark smooth reverb with rich sustain and a wide frequency range. This makes it ideal for anyone looking to replicate that iconic early 60s amp tone in a modern or restored setup. Durable construction with quality materials A rugged aluminium tray secures the custom-wound input and output transducers maintaining clean signal transfer. Internal wires are fitted with stress relief to reduce failure over time. Soft grommets help isolate the tank from cabinet vibrations protecting the reverb effect and improving stability. Drop-in ready for a wide range of amps The Type-4 comes with standard RCA connectors (white input red output) and multiple mounting holes for flexible installation. This makes it compatible with a broad range of classic and modern amp layouts and well suited for both upgrades and replacements. Made to perform and built to last Developed as a high-quality alternative after Accutronics ceased production the Type-4 captures the essential features of those early tanks while offering improved reliability. The hammertone finish mechanical design and tonal quality work together to deliver dependable performance for regular use on stage or in the studio.
