stay with me, my knowledge of these things is very weak.
basically i enjoy making mixtapes. i record the stuff off my hifi, from either cd's, vinyl or my ipod which are connected.

i've come across some fucking amazing cassettes from my yuff. some serious gold material, i.e. a whole transformers episode tape.

(obvious first q) is there anyway i can get this off the tape onto another, preferably with some sort of mixer where i could move the volume of the music over and under the tape at my wishing? (harder q) if so, what machinary will i need, and how much will it cost?
thank you very much.
