This is my shit-crap studio where I create mostly music for TV ads. But at least it works. It's a single room. I find that's sufficient for my needs, but have previously had a studio with a separate recording booth.
I solved a lot of cable problems, but not all of them. I have all the amps and cabs connected to an 8 amp, 4 cab switcher (I need to add another cab module since getting a 5th cab). This lets me put all the cables except the pedalboard cables behind the switcher and the amps; I use cable ties to bundle them.
I have some multi-cable wraps, but I don't use them as I find myself moving things around and dealing with the wraps turned into a PITA.
The one problem is I like to have the amps far enough away from the workstation that they're not on top of me while I operate the recording gear; this lets me hear through cans while recording as the amps are far enough away that the distance to them is helpful. The room is 33' long.
The compromise is that if I want to power the amps and pedalboard from the same power supply (I use the Furman PF1800-R with a 45 Amp power reservoir) so as to avoid ground loops and other power issues, I have to run a fairly long power cable and signal cable to the pedalboard.
To reduce the tripping hazard I wanted everything to lay flat, and had the power cord and signal cables wrapped with Flextech. They lay flat on the floor with this stuff. It's easy for me to deal with, but having one cable in the middle of the floor kind of sucks. Yet it's simple and effective this way.
I orient the cables front to back instead of left to right because that way I don't have to step over any cables on the way to the amps. Kind of a 'go with the traffic flow' thing. When I'm working I bundle these cables with velcro ties as well. If people are over, I have some cable ramps I can place over this cable, but I rarely need it.
It's far from perfect, and yet it's also kinda far from fucked up.
I'm mostly in the box these days with the workstation. I've bundled the cables under the workstation desk. It's a pretty clean setup. I have a 15 foot snake with 8 mic inputs that lives behind the rack. I generally run it along the wall behind the main keyboard desk to plug mics in, but if I'm recording myself playing an acoustic instrument, I often run it along the other wall and set up mic stands closer to the workstation so I can still operate the gear.
Here's another view of the amp nook area; I've been trying different spots for a couple of the amps, so the cables are bundled pretty loosely at the moment until I get that set more permanently.
Signal and power cables including snake are bundled separately, behind the workstation:
I use a 2 kVa balanced power supply with an isolation transformer by Equi-Tech. Each of the outlets is also isolated to avoid ground issues. Works great, reduced the noise floor by 6dB according to my Tech's scope. It doesn't show in this pic, but the power cables are also bundled and run along the back under the desk to avoid trip hazards.
