I've only sold one guitar to date. And most likely not to sell another because of this experience.
It was a Epiphone Strat copy, which i bought in the year 2000 as a package with an amp. It has an angled headstock, very much like those found on Jacksons. I can't remember the model, but i know they don't sell this anymore.
I was in Sec 2 when i bought that guitar. It didn't occur to me how i worked (or slaved) till midnight almost everyday at KFC, earning only $2.80/hour, going to school the next day all sleep-deprived and letting my studies slip, just to purchase that guitar, which was my first electric.
Now when i think back and recalled how hard i worked for it, i really regret selling it off. Such is the sentimental value of that axe =(
