Bigguy2017 Posted June 7, 2020 Share Posted June 7, 2020 That sounds like something going into oscillation. Most likely; dry joint/bad connection bad decoupling capacitors op-amp or transistor faulty faulty bright switch Have a really good look at the PCB, check the soldering, look for leaky/bulging caps. Unplug/replug all the connections, give them a squirt of Deoxit. Give all the wiring/connectors a wiggle to see if you can localise the problem. https://www.flyguitars.com/gibson/bass/RDartist_techinfo.php https://www.flyguitars.com/gibson/bass/RDartist_circuit_diagram.php That's a beast of a circuit diagram...
