New Adventures in K7 #35 : Yamaha MT120 is Acting Weird

Let's record an analogue electro EP on K7, episode 35. Where we find that 30 year old tape machines are, well, 30 years old. 2 tracks out of 4 aren’t recording properly anymore and I fear that the tape heads are at fault. On this video I try to fix the problem playing with the level and bias settings inside the box, to no avail.
