I told myself I'd sell this 60's Fender Ecco-fonics tape echo I have but at certain times (maybe a little less frequently than I would like) it really shines. It's a great dirty delay for guitars. It adds a lot of meat to the overall tone. It does a great job of building spontaneous repeats as is shown in this video. I brought this in as some ambient tape effect noise but ended up not using it in the end.
