I have been messing around with echo tape decks for lots of years,its fun, it all started when i heard a sound effects show on kpfa in berkley,ca, i live in sacramento, I stared wondering what would happen if I put two tape heads and amps in the same tape deck, through out the years I have tried several things including the vsc amp that radio shack sold as a tape deck that took out the pauses in speech, what that did was when you loop it it decades up or down depending on how the vsc is set, note the vcs tape amp is put in the receive or playback part ,it would not work while recoring, the vsc part only works in playback, I have just constructed a stereo echo deck out of an old soundsign top deck it has an speed controller that i took out of another deck
that was for sight impared persons ,it is really neat to mess with once i git the tape heads aligned properly ,i am also working on what i call a zip deck ,when done i hope it to be able to go fowards and backwords at the same speed ,I have built alot of echo decks and thing that the challange and fun of learning over just getting some software to do this is a lot better,besides when i was doing this there was really no software in the early 80's
I hope i explained this ok ,sorry im so long winded here I just had lots to say ,cus i read some person saying why any would want to waist time , the answer is learning and its just fun!
