Tc helicon Critical Mass. Suddenly is distorted, and has a subharmonic undertones that follow all settings. Changed all cords and power supply. Also used different PA and still get exact same results
There is a pre amp in that unit and it could have a bad filter circuit, it could also be a ground connection that has come loose. To properly check this you need a signal generator and a scope. If you don't have that equipment, you can open the unit and look for obvious issues like loose wires and burned or swollen parts.
