I made a discovery today. First time in ages I had no landlord in the house above my basement suite and no neighbours to annoy. Therefore the answer was turn both of my amps on, Quilter master maxed into my 2x12, my custom 50W tube head also master volume maxed into my 1x12 to see what it sounded like. Gain on both was around 9 o'clock so still clean.
The cleans were very pleasant once I dialed the volume in on the guitar (around 5-6) but as soon as I hit my OD pedal on and turned up the guitar volume to 9.5, the volume lift was massive (obviously) but the EQ went awry. My guitar sounded boomy and not pleasant until I turn the guitar volume back down to 5-6 but then my OD wasn't clipping as it's very volume pot sensitive (which I like). I was using my Gibson with 2 HB so I imagine hitting the pedal and preamp hard.
I understand the volume lift was due to the headroom on both amps being available so it will get louder but I don't understand the change in EQ.
I thought my bass EQ must be too high, tweaked the bass to the "point of most change" on both amps without touching the gain or master volume. Still didn't work well when I turned up the guitar volume to 9.5, just this ungodly bottom end like being plugged into a bass amp and all the note definition gone. Even the high strings just sounded muddy. Was probably hitting 90db or so (phone app db meter seems to max out at 90db) so near gig volume. It wasn't the nice compressed OD I was previously getting at the lower master volume and higher guitar volume.
Other things I have tried, turned the headroom down on both amps. The Quilter master control is also a headroom control so turned it down to 50W which is noon on the dial and my tube amp to 7W just to see if that fixed the issue.
So the question is, what was I hearing and what do I do about it if I want to use fuzz or OD pedals which are guitar volume sensitive? I can't run the guitar on 5-6 and get my OD pedal to sound acceptable at that volume, it needs to see 9.5 or full open volume control.
Speakers used: JBL D120F in the 1x12, EV 12L and Vintage 30 in the 2x12.
