Default Growling, howling, shrieking guitar amp

This Aria Loco bass combo 6126B is making plenty of output, but also unwanted noises as follows. With the volume at zero, moving the bass eq produces a growliing noise at full volume. Moving the mid controls makes an equally loud squawking sound and the treble makes a horrendous shriek. Tapping the boards has no effect. Not sure I will be able to find the circuit for this one, so any pointers please before I let my "phantom" fingers loose on it? Steve.
