1975 ELK Professional Echo Machine EM-4 Tape Echo Made in Japan civil war COLOR controls intensity of flangerMaker: ELK Model: EM 4 Echo Machine Condition: Vintage good Description: Here for your consideration is a 1975 ELK Professional Echo Machine EM 4 in good condition! This one is in good working order but the repeats are a bit "warbly". Could be in need of a new tape but we thought that it sounded cool, almost chorus like, so we left it as is. Pots and record playback heads have been thoroughly cleaned. A really fun, intersting, and vibey tape delay
