Sounds - Ok Complicated to get the sound you want, Be sure to DEMO First

Presets are OK .. the demo does this plugin a lot of justice to the point that it enticed me, an engineer of 20+ years into buying this plug-in. I missed the 14-day window and did not get to demo the plug-in. . You can get the same results with a delay and pitch shift plugin. I was not impressed as I spent a day or so trying to emulate the sounds featured in the video DEMO. Be sure to DEMO first!

Sounds great but buggy

As already mentioned some time ago, it's muted for the first 3 seconds of playback in Reaper. Hope it gets a fix one day.

“That” sound

I have so many imaging, spreader and widening plugins but this one is what I was looking for the whole time - it’s somewhat complicated but Chuck Zwickau’s presets are amazing - I wish they make this one native with Spark

My new doubler FX

It's a great tool to tick the vocal and ad chorus, dimension, any instrument. Very very useful to use as a creative tool as well

Useful to Add Depth and Character

A ringer for the analog version, the DMX is useful for adding big texture, but also for adding depth and presence to thicken vocals. I use it lots, but not always in an overt way.

The Missing Link!

This is the sound I was missing on my vocals. I’ve been hearing on records for years. I tried to make it happen with other plugins but could never get it to sound like what I was hearing. I knew the moment I added it to tracks. My clients love it.

Now I can kick it like the big dogs. Works great on just about everything!

Takes me right back into the 80s

I love this delay, instant 80s vocal vibes. Like it on guitars and drums equally. Also nice to add ambience (delays) for that reverby, roomy sound. Not doing a mix without it.

Very nice instant classic

Great presets and sound possibilities, though I could get the same results with other delay plugins.

Answer To My Prayers!

I've waited a long time hoping this would come out on UAD. Now it's here and it's truly the business! I Would’ve jumped in just for this one plugin but there's sooooo much more like the 480, Capitol Chambers, 224 and many other great titles. If your on UAD you're truly spoilt!

Back to the future

Instant 80’s vibe - and beyond, of course. Specially when paired with the RMX16, this toy can do real magic creating dimension and depth like no other plugins. Tasteful!

Exactly the sound I’ve been looking for, for 40 years.

I wish I had this unit to play with on the last few albums I made! It really was the sound we were looking for. I made heroic attempts to get a similar result by daisy-chaining different plug-ins and hardware. And it almost worked. These days the AMS DMX is always the first slot on my stereo bus! (just kidding... though actually...)

There is no tap tambo function, so it is inconvenient in live

Software is broken -- cannot be installed

I cannot install the latest UAD software, so therefore cannot use this plugin I bought. Tech support is no help. Having spent over $10k on UAD stuff, this is very very disappointing. The software WAS installed a while back, then became corrupted spontaneously. This is not the kind of service I expected from UAD. For these prices, they should be able to fix installation issues. This is not acceptable.

Amazing stereo effects

They did a great job with the presets on this one. So far, my favorite use is stereo-doubling with a short delay... the depth is incredible! While it can do crazy stuff, it is perfection for subtle widening and enlarging sounds

I love this thing!

I think I've used this on every mix since I got it. Adding a subtle effect this can give to any track is a game changer.
