The Field Kit FX Spring Tank from Koma Elektronik is a spring tank designed for use with the Field Kit FX. This is a large 8BB3C1B tank with 3 springs (each 23.5 cm long) and a long decay time of up to 4s. Characteristic for a spring reverb is the rattling, metallic sound, as known and appreciated since the 60s. We deliver this spring reverb tank with two pre-mounted RCA cables!
