Re: 30% chance of failure?(@AC) @mephistro
The graphic equalizer would have had zero effect on tape to tape recordings on a ghetto blaster. Equalizers sit in the signal chain just before the power amp. Even if there was an effect it's unlikely to have improved things - the signal isn't supposed to sound pleasing to your ears, there are discrete tones in use to convey data - all that matters is that they are discernible above the noise floor of the medium.
