Spring reverb system: The system is made of three separate springs with transmitter and receiver to obtain a very "dense" reverb sound. The system has an additional spring suspension to avoid undesired sounds caused by (small) bounces against the case. Connections via standard cinch/RCA female connectors. The system is used in the spring reverb module A-199.
