If your DMM has an AC range, likely it has a wide enough frequency response to reasonably measure a 400 Hz output. Using an inexpensive DMM, I measure about 3 Volts rms from the audio out of my SG 8. See picture on my post # 71 for peak to peak (about 9 Volts), rms Volts and frequency of my un-modified SG.
