I’ve made 3 cassette loops recently and all three of them have large drop outs in the audio where it loops. The tape itself looks physically perfect. The scotch tape is on the inside of the cassette tape as it should be. I’ve try this with two tape recorders and there is a drop out every time. What else could be causing this to not loop seamlessly?
I think maybe this has something to do with the erase head? Maybe I need to block it with something?
