DOEPFER A-199 SPRING REVERB : USED

COMES WITH : MODULE AND SPRING TANK ONLY Module A-199 is a spring reverb module. The reverb effect is electronically simulated by means of  3 spiral springs. Spring reverb systems have a very characteristic sound that is based on the (insufficient) mechanical properties of the springs like signal delays, audio resonances, limited frequency range, acoustic feedback behaviour, sensitivity to mechanical shocks and others.The 3-spring system used in the A-199 ensures a "dense" reverb because of the different properties of the three springs.The A-199 implies some special features that are not self-evident for spring reverb units:The reverb signal can be fed back to the input using the Feedback control. Even self-oscillation of the springs similiar to the self-oscillation of filters is available. The feedback loop can lead even via external modules like VCA, VCF, phaser, frequency shifter, vocoder, distortion/waveshaper, ring modulator and others. In this case the reverb output of the A-199
