here's an example of a song i recorded (off the bats brew 'the time is magic' album),
that used a 60 watt mesa boogie markIIb head thru Palmer PDI-09 for direct recording.... monitoring thru an attenuator set at whisper volume, the palmer takes the signal BEFORE the attenuator...
no mics on any of the electric guitar parts

Good guitar tones. Really good. The entire arrangement/production is excellent!

The only nit I could possibly pick - and I did listen on headphones - is dang I wish there was a way to get more controlled cross-talk. Some of the guitar tracks sound so isolated. And I don't think you can fix that with reverb - or at least I've not found a solution that works for me. The same is true for guitars recorded through loudspeakers and microphones, but the effect seems to be slightly less obvious.

Or maybe I just need my head examined???

Bat, that was excellent from top to bottom!
Liked the guitar a lot.

well, i wanted what i got, and worked to attain it...
 
i wanted total separation in this mix.  kinda like a steely dan mix. only rockier  :)
 
but, if i had wanted it to sound like 4 guitar players were actually playing together,
it would be very easy, to use a convolution reverb buss, and apply a bit to each individual guitar track,
basically would let them sound like they were all in the same room together at the same time.
 
 
and i do this on other mixes.
just not on this one.

but, back on topic,
this post i made was just to show what can be done with a simple direct box with a good cab filter built into it..
 
the weber i have, has a line out, and i can feed that directly to my interface and load a celestion 4x12 IR into the daw, and basically have the same thing as the UA device is doing, 
but with less control over the tonality of the thing.
but in my opinion, that happens at the amp, and how you set it for the purpose of direct recording.
 
i'd buy a custom low watt amp before i'd spend that much on a load box!
 
 

ONLY WORKS AT 44.1K?!

Someone on The Gear Page made a short demo using a Plexi clone into the OX.
Sounded amazingly good... very little work involved... and dead silent when recording.
 
Anyone played a Mesa Triple Crown?
The 50w model is about half the cost of the BE-100.
Had a Dual-Rec not too long ago.  Really didn't care for it's distortion (clean channel was nice).
The dirt sounded kind of "ratty" to me.  Hard to describe in words... just not complex or pleasant sounding distortion.
Tried tweaking it for weeks... 
The BE-100 OD pedal sounded nice thru the clean channel.  
 
The new 5150 with EL34s looks promising (at much lower cost).
I like the original 5150-III... though it has absurd amount of gain on the Red channel.
New models have separate volume for the Green and Blue channels (can now be properly balanced).
 

I have the Triple Crown 50w and absolutely love it.  Clean is great sounding whether you leave it on the clean setting or flip the switch to give it a little bit of extra grit, the blue lo-gain channel has a pretty good range from light breakup to decent older hard rock and even 80s metal gain levels, and the red hi-gain has plenty of gain on tap for anyone.  The MIDI switching capabilities are just icing on the cake.  It's got a lot of the British vibe of a Marshall, but with a Mesa take on it.  It doesn't have the earth shattering low end of a Recto, but it has enough for what I use and it is tighter and more pleasing to me.  Some have said that it sits somewhere between a Mark and Recto in tonality and that it kind of has it's own thing going on.  I was interested in that or the JP-2C and was leaning toward the TC50 based on listening to every clip I could find.  Then I called Mesa of Hollywood and asked them for comparison, and they said that the blue channel was really the big advantage.  The JP-2C, has is more like a clean channel with two hi-gain channels that are fairly similar in voicings (with a few options on each of course), whereas the blue channel on the TC50 does the in-between sounds much better.
 
I also had the 50w 5150 III with the 6L6.  Mine had been modded with concentric volume controls, which the EL34 now has stock.  I liked it a lot too, but the TC50 covers more range of tones in my opinion. The 5150 seemed a bit more metal tonally is one way of describing it.  Not that the TC50 can't get metal, it's just capable of a lot more range than just metal.
 
A buddy of mine recently picked up the new EL34 flavored 5150 III 50w and he is using that over the Peavey 6505+ that he was using.  I've only heard it once myself and I liked the tones he had.  Would like to play around with one for a bit myself to see how it compares to my old 6L6 version.  I know it's got plenty of gain for him to use the blue channel for pretty hi-gain rhythm, and he doesn't turn up the gain too much when he kicks it over to red for solos, so it's got that over the top gain structure mine had.
 
Sorry for the thread derail, but Jim asked, and since he's built my last two DAWs and offered me and countless other great advice over the years, I had to chime in. :)

Thanks for elaborating on the Triple-Crown and the other heads.  I appreciate it!
 
I've had the 50w 5150-III a couple times. 
For the cost, I always thought it was very good (especially the Blue Channel). 
Red has a crazy amount of gain.  In one of my 5150s, I changed preamp tube/s... which tamed the Red channel a bit.
 
I got the Triple-Crown and the OX.
Like the Triple-Crown a lot.  Your description is right on.
The OX makes recording guitar ridiculously quick/easy.
 
Spoke to a top-notch local player while at GC this past weekend.
He had the OX for a couple weeks... and has since sold his Kemper.
His take:
"With the Kemper, I sound like everyone else.  With the OX, I sound like me."
"It sounds/feels like playing thru a well mic'd amp/cab."
 
The OX has a 50w and 100w switch (software).  I didn't read about this before hand...
Tried a Friedman PT-20.  To me, it just didn't have enough "umph" to work well with the OX.
The Triple-Crown works much better.  So many good sounding options on both the amp and OX...
 
Went to GC last weekend (Saturday - probably the worst day) to checkout the new 5150 with EL-34s.
The guys at GC were kind of "down" on that head (for whatever reason). 
They had it plugged into a ratty cab... and I couldn't get a decent listen to it.
 
I think the OX has (re)started my G.A.S. for multiple tube amps.  
 
 

This is the thing I really wanted. Looks freakin' awesome. The bummer, at least to me, was the app, which you need to go deep with the product, is Mac only!
 
I had a credit card out too ...
 
Great video on the unit where the guy tests out the Vox speaker sims: https://www.youtube.com/watch?v=xbQZSMXtyMg

The lack of PC support for the Editor is pretty short-sighted...
In the meantime, you can use an iPad to control the OX (instead of a Mac).
