Up for sale is a gorgeous, amazing cosmetic condition SRE-555 tape echo with phenomenal chorus. The unit is in perfect working order, except for the Sound on Sound feature, which for some reason gets flooded with feedback when turned up. Not sure why. You can get echo when you use this with the SOS function turned up, but as soon as you turn the dial, it gets too loud with feedback/noise. I've confirmed that all echo channels work, though, as well as reverb and chorus....and the unit is in such nice cosmetic shape. This might be a quick and easy fix, but I'm selling it at a discount as is.100v unit includes free voltage converter so you can use the item immediately on arrival in your home country ($50 free value)
