You can use 8Ohm output from your head to captor 8. Then you can connect 16Ohm cab to the ATTENUATED output without worries. I believe, you can also use Through output, but then you have to use 16Ohm output from the head.
For recourding you can use line out jack, or XLR with Off switch, to be...
Bugeras - all of them. More or less emotionally, you know, Bugera...
Mesa Triaxis, Mesa Recording preamp
EVH LBX I - very loud and not loud enough at the same time, soundwise great
EVH 5150 III 50W 6L6 - not bad, but I expected more, it was literally buried by Engl Petrozza. The guy who...
Rectifier Recording Preamp. I bought it and sold it almost immediately. I was not impressed by the sound. But I'm not friends with the Mesas. IMHO, Engl E530 or Peavey Rockmaster, much better.
But as it looks, the Main jack can be a standard, non-switching jack with just Tip and Sleeve contacts, right?
Yes, of course
Also, I wonder if another loop between the T and S on the switching side of the Slave/Extension jack is necessary or even helpful, since when the Extension is not in...
You can solve this easily by using switched jack. I have found this schematic and modified it for your required wiring of two 16Ohm speakers in one cab. You must use upper jack to connect the first cab to the amp. Lower jack is for connecting the slave/extension. In that case don't forget to use...
Could be this one, but from the one pic I am not sure:

You know, voltage dividers are willing to work equally well with AC and DC voltages ;). Your wiring just adds serial resistance to the input resistance of the next stage, so it works to some extent, with few drawbacks.
However, unconnected terminal on the pot is generally a bad practice. If you...
I don't know, what preamps you use. However, output impedance of any preamp should be quite low. So lower impedance pot should be ok. But in general, anything from 10k up should work fine. I would use audio taper.
Marshall 2203KK - I wasn't able to use his potential. I lived in an apartment with nervous neighbors next door. And he played badly through the loader. He wanted to play at full power through the cab.
Engl Marty Friedman Inferno - brain damage got me and I sold it.
Enough has already been written, of course opinions differ. I had both Kemper and AxeFXIII. I sold the Axe, kept the Kemper and have no regrets. But I'm mostly a home player, I have no experience with live playing both. Kemper works for me to quickly find the sound I like. I bought three tube...
Just out of curiosity I bough 12-string Dean Vendetta. I was surprised, that some thrash riffing sounds pretty good, ACDC style rock as well. Just finished playing 10 mins ago and now have found this thread :)
