I have the RC-90 which works with it. If I'm not mistaken I think one of the remote options, maybe mute?, doesn't work with the 388. I could be wrong, but I think I remember hearing something like that. In any event I've used it many times and and the Record/Play/FF/RW/Stop etc all work with the 388. Make me a fair offer and it's yours. Private message me if interested.
