If I put the right-most treble on my dano EQ all the up and turn the EQ on and off, it makes a loud crackle, but it only does that when the reverb is all the way up. Also, when the EQ with treble is on, turning the reverb knob makes a squeaking sound at around 3' o clock. Also, the volume with the reverb all the way up is noticeably quieter than when the reverb is turned down. If the treble is turned down on the EQ, everything is fine. What could possible the reason why this is happening?
