Troubleshooting
In the unlikely event that your SVT-GS Gene Simmons Punisher should stop working properly (or just stop working), take
a few minutes to troubleshoot it before you call for service. You can save yourself a lot of time and sometimes money by
doing it yourself, and often the cure for the problem is something quite simple.
If the problem isn’t covered above, or if the steps led you here, then contact your Ampeg dealer for service informa-
tion. Also, you should refer your amp for servicing if it gets dropped, has liquid spilled into it, or sustains damage to its
power cord.
