The architecture of ARTHUR’s SPRING unit reverb offers the best of both worlds: digital delay and analog decay.

Digital delay provides a simple and efficient solution for delay lines that retard or echo the signal before being sent to the spring. However, when it comes to the more complex matter of reverberation, the good old spring still provides a more “natural” and musical solution. The spring unit includes six springs to give a rich reverb effect that also has a time-adjustable decay.

In addition to its function as an ARTHUR mixer module, the spring unit can also be used as a stand-alone unit, providing reverb for a signal from another mixer, or a guitar pedal, for example.
