Up there with the best!

I've had other effects units like this one in the past. All were good but this thing is pretty darn amazing especially considering the price I paid for it. (Thanks Sweetwater!) I bought it because primarily it was a Lexicon and because I really like the sound of the Lexicon reverb. Every studio I've ever been in had several Lexicon units and I was always impressed with the way they sounded. I finally bought one of my own and I must say this unit has to be one of the best values out there right now. You get premium quality effects, surround capability, remote control from your DAW (which is great for taking some load off of your system) S/PDIF I/O (a really cool feature by the way,) what I'll consider world class sound, and a fully featured dynamics section that is surprisingly musical! Twenty years ago you couldn't touch this level of quality and functionality without selling a limb! Today we have it made with gear like this. Could I compare this to the really high end reverb like the Lexicon PCM96 or Bricasti Design Model 7? Of course not but I'd have to say this unit is at least 80% of what those high end units are and for a fraction of the cost. I especially like the Plate Reverb on this unit. It's as smooth or as sharp as you want to make it. If you have enough spare I/O on our interface or enough AUX's on your mixer, you can really take full advantage of all the I/O on this unit and do some really neat sounding things. While I don't consider myself a professional in the audio field (yet) I've been into this for many years and can tell the difference between average ho-hum sounding gear and something that's unique. This unit is truly unique because of the quality of it's sound at it's price point. I I highly recommend it to anyone that's looking for a good outboard multi effects unit at a good price. Not everything that's affordable is ho-hum and this unit is proof of that for sure! You really get a lot for your money in both functionality and quality of the sound. Not to mention this thing is built far better than what I thought it would be. I was leery about how much I was going to like this unit due to past experiences with purchasing other effects in this price range. While the other brands I've heard, used, and purchased were okay, they were just "Okay." (The only thing to be aware of with this unit is make sure you leave a vent space in your rack since this unit runs a little on the warm side.) I was pleasantly surprised and delighted with this one. It's not only a winner but a keeper! Needless to say it's going to be a permanent part of my rack! Buy with confidence!

Replaced my old, dead LXP-15

I was really surprised at how great this unit sounded especially in comparison. Hotter output, no noise and easy to use. It is like having two units instead of just the one with the ability to use two unique processors at once.

It's Lexicon - the name alone should say everything!!

Now Lexicon has come up with a QUAD independent engine design in a single rack space without sacrificing any of the amazing verbs and other specialty sounds that made Lexicon famous. The labelling of the input and output section can be a bit confusing, but if you just look at the input/output 1 &2 as simply 1 &2, then the "rear" inputs/outputs as 3&4, you're all good to go. The if you need four independent signal paths, - no problem dial up one of the many four independent signal path settings and then just insert whatever effects you want into those chains, and you're good to go.
