I had no clue where to post this, it's kinda of a weird question. So when I'm sitting at my computer sometimes I have my [electric] guitar and I have my wrists on the PB and if my forearm lowers it hits the neck of the guitar along with one string. I then feel a shock where my arm touched the string. Why question is generally this: Is that bad for my PB? Will it hurt it? I suppose I should try it touching other metal things or try it with the computer unplugged. So does this have any negative effects other than hurting my arm?
