I don't need the money at all (I'm not even sure how much they are worth).
I just don't have room for them. They are taking up valuable space in my basement-turned-guitar building shop.
I have them all archived as .mp3s as it is. This is a project my father undertook in the years before he died. Unfortunately, being miserly as he was, he bought the cheapest rig he could to record them with, so the mp3 quality isn't the best.
My sister is sick of looking at them too. It's definitely not music she would listen to, and she would love for them to just disappear. I'm a bit sentimental about them, but that is waning lately.
