Richard,
His readings were way off. Use the troubleshooting guide voltages for the correct values (found under the “documents” tab of the Quaverato page on our site”.
To use a multimeter to measure DC voltage (all the voltages to measure on the Quaverato are DC) first make sure the meter is set to the DC voltage (V) setting, not milivolts (mV) (if your meter has a “mV” setting).
Put the black probe (the negative probe) on a 0 volt point in the circuit…we call this the circuit “ground” or “common”. You can use the fist pin of the input or output jacks (the pin closest to the part of the jack with the hole for the guitar cable). Or you can use the point on the pcb that the ground lug wire is soldered to.
Put the red probe on the point you want to test. The voltage difference between these 2 points will be given by the meter.
When you test the voltages on the pins of the IC make sure to not be touching 2 pins at once. Place your red probe on the IC pins right where it comes out of the IC’s body. Make sure the depth knob is all the way counter clockwise. That’s the only knob that needs to be in a particular position.
Good luck!
