I am not really looking for more volume, I am looking for more headroom and a slightly bigger sonic footprint.
Maybe I will try turning my amp up more and pulling back on my guitar volume even more.
Nice amp! There are a number of solder joints that have been re-done... was it messed with, then restored at some point?
"Bigger sonic footprint" sounds like a DR103. At that volume (master full up, preamp halfway) you are probably starting to get a little bit of compression with the '504. A '103 will compress less. I like both my '504 and my '103, but the '103 just has more "girth" to it. Even if it's
only 3dB louder, it's terrifying (reaching-for-the-earplugs loud) at full blast, whereas the '504 is
almost tolerable.
I don't know if cranking the preamp and turning the guitar down will do what you want, but it's worth experimenting with. FWIW, I crank the channel volumes and roll down the guitar to clean it up, ala Townshend.
