Glad I bought 2

You never think you need one until you wan't a brighter vocal. I needed to do a voice over that was modern and bright without the SS...This did the trick at the source.No need for a plug in

No brainer

I think I have almost every de-essing plugin there is, even the LSR emulation of the 902. They all get used at various times depending on how specific or problematic the esses are. I saw this here and I figured why not, worst case it'll function as a cover for an empty space in the 500 rack and it's cheaper than a plugin. I couldn't be more blown away, literally set and forget and works better than plugins (surprisingly even beat my favorite, the amazing FabFilter Pro DS). My main client uses a Sony C800g and while it's great for him the sibilance can be murder with some guest vocalists. After I mix or two I decided to experiment with moving it to the tracking chain before the compressor. Instant win, didn't degrade the sound, only killed the sibilants. While not as exciting as a preamp or compressor I feel like this is the best secret weapon anyone wanting to get smooth vocals should have. I can't say how close to a 902 it is as it's been a long time since I used one but I'm happy either way. Also works great on acoustic guitars to minimize fret noise. I'm ordering another.

Sssssure works for me!

Great de-esser, the dbx 520 sounds very natural and it,s a set and forget type of piece, once you know your target frequency range. Just sweep the range on a pre-recorded track that,s sibilant and you,ll find it as fast as it takes to read this! So now I can use any condenser mic in my locker, where as before I,d skip on. Made all my condenser mics usable again for vocals. Bring On the Sssssssss, cause this will tame them. Thanks, Chris!

I love it!

It is cheap, it works perfectly, just remove the silbants or the frequency selected, what more i can say! It is great, you cannot be wrong with it. This is way better than the de-esser plugins, and it does not destroy the vocals! .... just the selected frequency!

As good as the classic 902 De-Esser

This is my favorite hardware de-sser. I use to own the 902 and this is spot on. You can'r beat the price and it gets the job done!
