A 1970 Gibbs spring reverb tank (2 spring model) was sampled 14 times. This was probably taken from a Hammond organ, but the same model was used in Fender gear also. Different hardware setups were used, along with a little digital and analog trickery (in some programs), to get a variety of tonal possibilities, all still true to the basic spring sound. In some cases, feedback was used (with 2 different paths), in others cassette tapes were used, and in some cases objects were placed on or wedged between the springs to cause different resonances and decay behaviors. Some employed a method to shift the frequency response of the spring up or down. Check the manual for detailed descriptions of how each effect was made.
