Went to look at a guitar yesterday and I'm trying to diagnose some of the problems it had before I potentially buy it. It's an LTD Alexi laiho 200 so single volume control and a single EMG 81 in the bridge position.
Guitar has very little volume when plugged in. The amp and the lead were tested successfully with other guitars so it's not that. Also tested with a number of new batteries for the 81 so not that either. The input jack was loose so owner had previously resoldered it, found this problem, reversed the wiring of the jack to see if that was problem, and found no difference.
The volume control does nothing, doesn't lower, higher or turn the volume off when you use it, guitar just stays at a constantly low volume. Also, when you touch the metal dial for the volume control you get earth hum. That's pretty much all the info I have as it was late and I still had a 90min drive home to do so only had time for a quick look.
I'm not afraid of a fixer-upper or redoing the wiring as I've done a few guitars in the past but I've never come across this combination of problems before. The wiring definitely needs to be redone but my fear is that the pickup is somehow damaged too, which I know is rare, so I'm wondering if anyone with a bit more experience can enlighten me as to what exactly is the cause of the problems so I can fugure out if it's worth pursuing.
