My bedroom is seldom where I play at home.
Living room:
Supro,About 2' away, on floor, or amp stand, facing my general direction.
Dining room:
Supro or 5E5on Floor or amp stand, about 2to 8 feet away. I walk around more with 5e5, I kinda know where to put the knobs for whichever guitar then use the guitar knobs n switches. If I needed it louder (unlikely unless I was recording specifically for breakup and not just playing for fun) I'd pace around more I suppose.
The Supro I stay closer to if I'm tinkering.
Kitchen:
Supro on counter facing me, or amp stand angled up the steps, where I'll sit. 5e5 or 75 on floor 5'ish away.
Upstairs hallway:
I'll occasionally put the 75 in the hallway facing toward hall, and open all the doors just so I can pace around while I play. I'm sure this would sound awful to record.
Bedroom:
My Fender 75 is large, and normally in my bedroom. If I want overkill power and or my best reverb, i sit it within 6' of myself on the floor or dresser.
It doesn't like amp stands, no idea why. At practices I used to pop it on garage workbench. Dive gigs either on floor or up on a nearby pool table.
If you know where you want your amp knobs, you can be further away. I first bought a 25' cable so I could be a room away from my AB165 Bassman and use the teles knobs to change sounds.
If you aren't as attached to your settings or change areas often, closer is better.
From what you describe, you're not a "this setting for this guitar, done!" Sort of player with the amp in question, so closer seems better.
What's the amp? Extension cabinet sounds like a potential answer.
