Hello everyone, this is my first post here. A friend brought his 1980's vintage aria bass to me to fix. It's an Aria Pro II. It has active electronics and the pickups are P-J combination. It also has a pickup blend knob, a volume knob that clicks when turned fully off, a mini switch, and what seem to be two eq knobs with multiple detentes. When I got it, it made no sound. I opened it up and several wires were broken due to loose pots and input jack. I soldered everything back into place and put in a good 9 volt (7.5 volts on my meter). The bass now sounds like I'm playing it through a fuzz box. For good measure, I tried a brand new 9 volt, but got the same result. As it stands now, the bass distorts, it has a huge transient when turning the volume on past the click point, and neither the eq's nor the switch do much at all tone wise. It has circuit board with an opamp, two transistors, and many capacitors and resistors. They are discrete, so they can be serviced separately. Can anyone suggest where I should start trouble shooting this?
thank,
