As one user described on a different forum, my 45000 has started making a “semi-rhythmic buzz-clicking that gets recorded along with the input signal.” I’ve checked everything in my chain — replaced all cords, power supplies, even bought a brand new mixer — and I’m confident it’s the internal clock of the 45000. The noise’s speed correlates with the tempo knob.
I’ve turned the “click” volume knob down, but the sound is still coming through, leading me to believe there’s bad circuitry.

Any insight would be appreciated. Should I send it back for a fix?

Thanks,
