when actively driving a fuzz face, is it normal for the Q2 bias point to change from 4.5 to 3 or so? It settles back to 4.5 when not playing. Is this ok or is something off?

I would have thought the bias point wouldnt change and that the audio signal would just hover around that point. Or is the audio signal just shifting the measurement?

This is on an NPN silicon fuzz face
