Troubleshooting
In the unlikely event that your SVT-4 PRO should malfunction, take a few minutes to
troubleshoot it before you call for service. You can save yourself time and 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 lead you here, then contact your
Ampeg dealer for service information. Also, you should refer the amp for servicing if it
gets dropped, has liquid spilled into it, or sustains damage to its power cord.
