Awesome sounding amp !

The sound of this great amp simulator helped me to get a guitar instrumental on a T.V. show ! Sounds so natural !!! Here is the link to the instrumental.

Just WOW!!!

I'm not a guitar player but brought over a couple of friends who are to try out some of these VST plug-in's. I demoed 3 different ones for the guys, and when I got to the Friedman, we were ALL blown away by the town this thing produces.

It literally sounded like the most beautiful amplifier I had ever heard! My 2 guys even mentioned how clean/clear it sounded and how it sounded like a cabinet sitting in my studio coming from my monitors. The guys are now asking how much does a UAD setup with this VST cost.....just spectacular.

Best algorithm in the business

I sold my Fractal Axe-FX 3 because of this amp sim. It’s response is unparalleled and it’s tones and versatility perfect for the clean to heavy crunch guitarist. No need for other rack gear with plugins this good!

BEST UAD guitart amp simulation plug-in, ever.

I've bought, about 10 guitar amp plug-ins, only in UA.
But I can assure you one thing. This is it. The best, the most versatile, pleasing sound.
It is creamy, does not go too far, any sound in preset will be just good to go.
Just demo this now!

One of the best

Amp sims are getting better, especially the ones from Brainworx. The newer UA offerings all sound better than older sims that try to do everything in one package.
So far, I have the Chandler, the Ampeg collection, the ENGL 765 RT (and the native VS), the Fender 55 Tweed, the Softube Marshall Plexi Super Lead 1959 and now the Friedman Buxom Betty (I also have various native bx plugins that are good; the bassdude gets a lot of use).
I haven't had much time with the Fender or the ENGL VS yet; the Marshall is okay but nothing special. When using a UAD plugin, I'd usually reach for the Chandler first, then the Engel RT; (for bass, whatever Ampeg seems appropriate). IMO, those are the best of my current UAD collection - Until I tried the Friedman Buxom Betty.
For a single channel amp, it is not only super versatile, it sounds flat out great. Killer. REAL. And I don't even have Unison technology (though I do record guitar & bass through high end tube preamps before they hit the plugin).
The Betty shines on many fronts, but the thing that stands out for me is the dynamic response across frequencies: the highs shimmer without being harsh, the mids are present but not mushy, and the lows are chunky yet controlled. Unlike a lot of other amp plugins, the tone stack is tuned just right for the Betty. And the tube response (distortion) sounds like real amp - very dynamic.
For those worried about the limitations of a single channel amp, you can store different settings in the 4 slots (A, B, C, D) and switch between them via remote control; I set this up in Cubase with a foot pedal - heaven!
My only complaint is the lack of a dedicated FX loop, but this is true of almost every amp plugin and it can be set up with a bit of time and an extra converter I/O.
I still plan on using other sims in the future, but the Betty has become my 'go to' amp for now.

Amp in the box

Very nice amp, sound great as standalone and with my Mesa rectifier recording preamp as cab sim. God work!)

Sounds like a real amp!

It's just amazing how this plugin works with real guitar pedals! It doesn't matter overdrive or distortion, it is sounds like you are playing through a real amp! Love it!

Good))) MESA + IR

Really good stuff, great additions to my Mesa Recording Preamp Rectifier for IR response! And as stand alone too!

As good as expected

without ever played the real amp, I am pretty shure that this plugin nailed that fantastic sound.

Superb sounding amplifier!

Probably the best UAD amp plugin. Very easy to dial in, sits perfectly in mix. Touch responsive, sweet sounding, very clear. Beautiful overtones when pushed. I have the BE50 deluxe which has the Buxom Betty clean channel, it is identical. Try it!

Great model. Excellent clean tones. I can get close to some AC 30 sounds with some tweaking. Love it!!

Nice One.

Do not own a Hardware one, but I like the Software for that price in my collection. I have used the Demo before, into different songs and fits well.
This production was not a Heavy Metal production, so i would chose a ENGL plugin in that case or Hardware Amp.

Great sound as real

It really sounds like an amplifier rather than a plugin, very impressive.

Great Sound - Versatile

Just picked up Buxom Betty. Initially I was not sure about the purchase because I already have a number of UA amp sims that provide me with a wide variety on tones. I'm so glad I did! This is a great amp that has great tone, texture and flexibility. I've already used it on two of my tracks. Sits right in the mix. Another great addition!

Stunning cleans - loves my pedals

I have a large collection of quality dirt pedals, and wanted something that could really bring them to life in recording. This is that something. Great feel, great tone, great texture. Outstanding.

The best by far!

This amp sounds incredible. For an amp. Not “sounds good for a plug-in”. This plug-in sounds good enough to think of it as an amp, because that’s what you’re getting. Had a client who is hard core real amps and pedals and has a really nice and expensive collection actually record for the first time through a sound he liked in a plug-in, using this. But it. It also takes pedals like an amp does.
