SVT-3PRO Bass Guitar Amplifier
In the unlikely event that your SVT-3PRO 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.
The SVT-3PRO is covered with sheet metal and aluminum, not unlike robots, spaceships and other cool things.
Clean with a dry, lint-free cloth.
Never spray cleaning agents on the SVT-3PRO. Avoid abrasive cleansers which would
damage the ﬁnish.
