Sounds from there and where!

Very multiple unison amp. In my daily use. All in one box, from vintage to these days, wit fx or without, cool cleans and strong overdrives!

Strogly recommended!

Best UAD guitar amp (I think...)

I have a few more UAD guitar plug-ins. This one is the most diverse that I have.
To go down all the different cabinets and mic setups is really helping to quickly find the right sound.

Buxom Betty is Best of the Bunch

My regular real amp is a silver-face Fender Custom Vibrolux Reverb-Amp, but I needed something for recording late nights without bothering my housemate. I demoed the Buxom Betty against all of the other UAD guitar amp plugins for a week (including the Fender Tweed which sounded thin to me) and liked this one best. Although it's a little bottom heavy and needs some EQ to avoid getting muddy, especially with humbuckers, it's the most "alive" sounding plugin in the bunch for clean and low-to-medium gain to my ears. Not as good as a real cranked amp, of course, but still nice. Very smooth and spongy for mellower styles of music.

Awesome amp.

This is a great sounding alternative or addition to the Marshall collection, providing similar but different tonal options. The cabinet IR's are fantastic, you almost feel the air moving, and it reacts very faithfully when used in Unison.

Versatile, Modern Amp

I'm a longtime Fender player, both guitars and amps, and I tend to favor cleaner tones to dirty ones. My go-to amps are wrapped in tweed and sound warm and buttery with vintage vibe for days. The Buxom Betty struck me right away as more transparent and honest. The clean sounds don't seem as shaped as those I'm used to hearing, and the difference feels modern to me. It's similar to the difference between 75-year-old acoustic and a modern pro model. Both have their place, but the new one likely benefits from technical advances, updated production practices, and better materials sourcing. The result is an instrument that's more balanced and capable (though perhaps with less soul). My early impressions of the Buxom Betty are similar. It's a workhorse amp with great versatility and a pretty honest tone signature.

Forget all the others. This is the one.

Activated the demos for most of the UAD guitar amp plugins just to decide which one I was gonna get. Honestly, I think most of them sound like crap (especially the Softube stuff), but this one is the opposite. Never used a better amp plugin! I'm really happy about this purchase.

One of the best software amps I've ever used

I love the UAD Friedman amps in general, but the Buxom Betty in particular is one of the best software amps I've ever used. Period. It sounds great and is very versatile, I've even run through pedals before going into it and that works amazingly well (likely due to the front end design of the UA Apollo). This amp sim actually *feels* like playing into a real amp, it feels that extra little bit responsive. For clean or slightly overdriven tones, the Buxom Betty is my go-to.

Great amp, great tone, a lot of options!

I did not expect to be blown away by this amp, but the basic tone is really nice. I especially like all the options with the mic & cab selection and especially the automatic toggle function making finding the right tone a breeze. I never tried the original amp, but after trying the UA emulation I am definitely intrigued. Combine this with the TS808 from the Distortion bundle and you have a wide range of tones. Good job UA!

UA keeps this ol' boy smiling.

In a fortunate confluence of events, I purchased the upgraded Helios EQ and found that it worked wonders with UA's Marshall Collection. So, I naturally wanted to hear it with something that wasn't a Marshall (call me crazy.) After reading the reviews of Buxom Betty, I gave it a try and it was an instant BUY. Besides, who wouldn't want an amp called Buxom Betty? Now she's my go-to and the Marshalls have become my "on the side."
Either way, UA keeps this ol' boy smiling.
