AKAI SX C-90 10 pack end of line cassette & sound 

While in my opinion the cassette still is a bit hissy, I have to add , that it sounded worse than it had to . And worse than usual. While the video was uploading, I have realised that I have used a faulty/ crappy 6.35mm to 3.5mm adaptor in the tape loop. I was meant to throw it out, yet it got mixed up with the good adaptors ! And that is the main reason the sound is worse than usual and worse than it had to be.!

I think you can try a little more level to prevent hiss, maybe it's sounds good at +2! anyway interesting video
