Spring Reverb including tank found in the Roland Space Echo series & System 100, 4-band equalizer
Stereopings Spring Reverb module is the result of months of research and development to find a universal solution to get any spring reverb tank integrated into the eurorack. We tested it with more than 30 mostly completely different tanks with input impedances from 8 up to 1500 Ohm, output impedances from 500 up to 10 kOhm, input- / output jacks insulated or grounded – up to now, each tank did it.
In spite of all the promises digital technology make us, many musicians and producers still sware on the original spring reverb sound. Unfortunately there is a huge variety of reverb-tanks with different input and output impedances, insulated or grounded input or output jacks. On the other side, the web is full of schematics which are meant to work only with especially this or that sort of tank.
Increasingly uncertain and bugged, we started to build something ‘universal’. The schematics for this module is therefore not developed from ground up. We just experimented with existing schemes, tried to simplify things where possible, added a versatile 4-band equalizer and the result was this Spring Reverb module.
