Features
The BeniDub Spring Amp III is designed to bridge the gap between audio mixers and spring reverb tank, offering dynamic filtering options in an intuitive and ready-to-play package. This new all-in-one dub reverb and filter machine features a full suite of powerful and intuitive controls, making it easy to dial in your favorite spring reverb tones in the studio or on stage. The BeniDub Spring Amp III builds up on its predecessor, adding up new features and better playability, with a push-button switch for routing settings, allowing you to place the filter before or after the spring tank for more mellow or dramatic swings. This updated version also features an in-built soft clip circuit on both input and filter which lets you push your sound even further without damaging your performance and get that classic, warm, musically pleasing saturation which adds rich complexity to your swells.
All features are clickless and the circuit has an inbuilt low noise filter alongside Class-A discrete components. A 7.5W constant current amplifier drives 8ohm input reverb tanks for maximum volume and best treble response. The Spring Amp III has an inbuilt analog filter with controls on its cutoff, resonance, and modulation. It features a crossfader between low-pass and high-pass filters outputs and a click-less switch to place the filter before or after the spring tank. It is designed to be a plug-and-play dub reverb effect, delivering the classic dub sound instantly upon connection.
The Spring Amp III needs to be connected to a compatible spring-tank in order to work correctly. Please never connect the Spring Amp III to a tank without making sure that it is compatible.
