EM-808D ECHO MACHINE - LONG LIFE TAPE ECHO

This was the top of the line unit from Guyatone in the day. The big brother to the EM-606. It is has longer delays (thus the long life) that can go into self feedback delays. I have played both the 606s and the 808s, and they are both nice machines. I find the 808 a bit beefier, with more input options, and more echo delay versatility to dial in your sound.
