No need to jumper the channels as the volumes are extremely interactive. I tend to run the channel volume I jack into between 9:00 and noon with the unjacked channel dimed up full on as it scoops the mids and gives more clarity with less chaos. I ride my guitars volume as it interacts so well with the amp.
Reducing the full on unplugged channel just a tiny bit is like everything full up Neil Young/Billy Gibbons growl, howl and saggy attack.
I used a nice Tweed Deluxe clone for a while and loved it. As mentioned earlier, these days it's close to perfect as you can get. You can get real amp overdrive at a reasonable level in most decent clubs without pissing off the sound worker or club owner--even audiences don't want too loud. I played mine with a Celestion Blue for the reasons mentioned here as well. They are far more efficient than the old (even vintage) Jensens which gets you a far more dynamic experience at low volumes, plus more actual volume from the amp (several dBs being that the Blue is rated over 100 dB effficiency vs low 90s for Jensen.
FWIW, My current main gigging amps are similar 'cause I like to have reverb on tap. #1 go-to is a '72 Princeton Reverb with a 12" Celestion Blue!
