Thanks Lester,
I guess Scotty on Star Trek was right after all ....'You cannae change the laws of physics!'
I don't think I'll ever be brave enough (or wealthy enough) to splash out on a Kemper, so I keep my eyes open for cheaper solutions. There seems to be a rash of options nowadays and although that's better than no options its really confusing which way to go. I really can't record loud amps, and although I fancied building an isolation cab and stuffing it in my garage, that has its own practical issues. I'd love to run one 'jet engine loud' like Time Pierce does, but that's not going to happen

Back to earth, plain guitar or through most pedals sounds and feels anaemic, so I don't do it. I get some mileage from a Boss Katana that I can mic or take a DI from, but it doesn't put a big smile on my face. I can get heavy rocky sounds from a Moor Live pedal which is good because its reasonably quiet but I'm not so keen on the clean/edgy sounds. I've tried an external cab sim pedal (Nux Solid Studio) but it tends to sound boxy to me. I've also tried the free Two Notes Wall Of Sound software, but that also sounds boxy to me. I've got amp sims in Cubase and also Guitar Rig 5, and I can get some really good results from them too. However, there's something far less immediate about playing through any software though, and although the flexibility of being able to change the sounds after recording is fantastic, the DAW latency can be awkward. Its still not like playing through an amp. I've got an old Marshall JMP1 rack preamp, and its not bad, but not wonderful either (and the built-in cab sim isn't good), but at least its immediate.
Recently, I've been wondering whether to buy a Two Notes Torpedo Cab M+, which claims to be the perfect pedal platform (and I have tons of pedals). Oh, and don't forget the Humboldt Simplifier, and the Atomic Ampli-Firebox. Both impressive!
Then again, the Two Notes Captor X would allow me to run a proper amp (and I have several) into it and get the immediacy plus silent recording. I'm not so keen on anything with phone app control (I'm a Luddite) but at the moment, that would be my favoured option. Sadly, they're not cheap, so I'd better save up!
Of course, there's always the other end of the market, the Joyo Preamp House, and its hard to pick too many holes in what this offers for the price.

Maybe there are too many options, and Scotty would probably laugh at all of this debate!
Anyway, I hope your quest for tone satisfaction eventually leads you to something great. Let us know. Good luck!
