This is all that and then some! I've used it on vocals, guitars bass, DRUMS and it is now my go-to pre. So many USEFUL features. I'm running 4 other pre's into the 4 1/4" ins and feeding the ADAT line to my interface for an all in one unit. The 4 inserts are sweet for adding noise gates to mics if needed or any other rack unit. The compressor is sweet...gets the job done without over doing it. The tube/Trans feature is SWEEEET! his unit made one helluva an impressive sonic change in my sound and recordings. And I DO love that UA sound! I see another in my future! Highly recommended....U DIG...!

"It could have been a nice addition to the studio if it wasn't for the terrible quality control of these units."

Sound
Sound was good. Very clean.
Features
The tube blend feature is nice. It added fullness, maybe a touch boomy on the 100-200Hz range. We tried it on acoustics and vocals. Many cool output and insert possibilities.
Ease of Use
After a little tweaking you can get some decent tones.
Quality
We tried three units!! From noisy inserts, to wacky input levels between channels and terrible gain stages like moving the knob a hair and the gain would jump up.
Value
WIth these quality control issues for a 2000 dollar unit I can not recommend it. And I had high hopes for it because Universal Audio makes great products. Very disappointed.
Manufacturer Support
I just returned it to Zzounds. I lost a month over these three attempts. Gotta give kudos to Zzounds with the Returns department. They were prompt and no hassle.

"UA 4-710d so far so amazing"

Overall: 4.5 out of 5 stars

Stacked two of these for 8 ch on drums. Line outs of the bottom 4ch. into the top preamps 5-8 so all 8 ch. coming in ADAT to the ferrofish pulse 16dx. Clarity, so much clarity. With no EQ on drums, just some fast comp turned on some channels, sounds amazing pre mixing. Tube and solid state blending is amazing for dialing in your tone. All tube drum recordings are changing my life. Price keeps going up so really its a high end preamp and a great investment. I have 2 and they are both great, never heard of manufacturing problems anywhere except the other review on zZounds.. maybe user error or a heavy handed approach? 4 to 5 stars all around
