"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.
