I was jamming with a friend laste week and I use Monster Cables and I was using my JP6 and we were going for a beer break I took the cord out but part of the cable stayed in my JP! I guess Monster Cable uses a "pin" end on the 1/4 inch so that some how is not coming out of my guitar. Its stuck! So I contacted both EBMM and Monster Cable and the cost for repair will be about $70.00 I was told by EBMM customer service. and MC is going to help me file a claim for the damages. So it will be taken care of but man this sucks.
