homemade, long delay tape player modification

[Kriist@aol.com]

has anybody modified a regular home tape deck(with simul record/play 
feature)to allow for really long delay times(no layering, as in 
frippetronics 
stuff)
just a LONG delay
i assume it would have to take the tape out and run it through lots of 
internal loops , and perhaps run the tape even slower than normal

so that one can can play into the thing(with perhaps only the WET from 
some 
odd effect going into the deck)and , say, 10min later have some freaky 
accompinament with what your playing in real time
