GK Backline 600 has power but no sound
Well, although I've been playing bass guitar for many years, I'm not at all knowledgeable when it comes to the electronic end. The other day, my GK Backline 600 started cutting out on me the other day until it stopped performing altogether. I assumed it was my battery for active pickups, but the passive bass resulted in nothing, as well.
Anyway, the power light comes on, but that is that. This is not under warranty and I would rather not put $200 into a $300 head, eh? The local repair wizard says $95 USD plus parts to fix her, so any constructive advice would be appreciated for my doorstop...er, non-functioning bass head.
