I absoluitely love it

I recently acquired a ruby and it really does remind me of when I used to run an amp!

I am blown away by the realism. I do wish I had more visibility on and the ability to choose a different cab each side and maybe even blend the same amp but the different channels left and right but otherwise without any extra editing this thing is a beast still.

Really Good, Could be great

Firstly, the sounds are really cool. Other people have said it, but this by far the most "amp like" modeler. I've tried them all, but I'm coming from a square black box modeler that gave me three options and full midi control. I really took advantage of the midi in that box and loved being able to use midi switching to turn the drive knob up and down. I wish all of the UAFX pedals had midi and I do think it's a mistake. But since I think it's impossible for them to add that functionality later, I'll concentrate on what could actually be improved while letting UA stick to their no midi philosophy.

1) Add a way to change which microphone is used on which speaker (I know it's possible - artist presets show it is). I like the speaker choices, but sometimes I'd like a different microphone on that speaker.
2)Add a way to make basic eq changes. - A high pass and low pass filter would get us 90% of the way (again eq changes are there in the artist presets, I know it's possible).
3. Please let me use the tremolo on the brilliant channel. I know why you just wanted the amps to be as they are and be faithful to the specifics, but I could replace the trem pedal on my board if I could use ruby's tremolo with the brilliant channel.

So yes, I'd love full midi implementation, I understand that will not happen. But these three changes would make this that best amp modeler on the market even without midi and all of these are possible and dare I say - easy - to implement from a software perspective. The only reason I'm even writing this is because I think that UA listens to its customers. I really like the Ruby. I want to keep it. I sincerely hope there is more development on it coming. Thanks for making a really great sounding amp.

Amazing in every way!


I followed the release of this unit and was intrigued, so I decided to visit my local store-and milliseconds after plugging in, knew this was VERY different than any simulation previously available. After 35 years of owning some of the finest vintage gear-along with a strong desire to modernize my recoding set up; I can say this little pedal has made more of an impact than I could have imagined. The VX sounds are all there-and the adjustability is far better than owning 3 different AC-30’s. However, the real magic is in the feel. Many products had touted “real amp-like” feel over the years, but it my experience-the Ruby delivers better than anything else. Real goosebumps. Since purchasing 2 weeks ago, I’ve logged more hours playing the Ruby than anything else I own. Thank You to the UA Team! Now, please come out with a Pedal that emulates the “other” British amp company:)
