"A Great Sounding Pre Loaded With Pro Features!!"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I will be satisfied for many years and would definitely replace it if something were to happen to it. It's a must have item if you're looking for a pro sound. I have a Great River ME-1NV which is also an incredible mic pre but there's a huge difference in the price. The GR is no better than this pre. They both have a sound of their own and all usable.

The sound of this pre is awesome. Of course you'll need to change the chinese tubes that come stock with the unit to take it to another level but fresh out of the box this pre will amaze you. I ordered a matched pair of Tung-Sol tubes for it.

I can't believe how many features there are on this thing. You can really sculpt the sound of the source material in many ways. Variable input impedance for mics, selectable plate voltage, xlr inputs/outputs and 1/4" TRS outs and so much more. Incredible for the money.

Ease of Use
Very easy. Just plug and play. It does what a pre should do. deliver exceptional tone and sound. It looks great too.

It's made very well. The knobs are heavy duty and rock solid. Seems to me with proper care and handling this pre will provide many years of trouble free service. I do studio work only so it won't be going out on the road.

The best "bang for the buck pre" out there IMHO.

Manufacturer Support
I gave this category a 5 as I've never read more had to deal with support. I own a few ART products and never had any problems with anything.

The Wow Factor
Like I said it looks and feels great. Most importantly the sound is what a pre is all about though.
