"Awesome unit for the money!"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
Overall I'm super happy with this unit. BUY ONE! or two or three...
This unit has a very nice warm sound - I use it for voice work and am very happy with the sound of the tube pre-amp.
Excellent feature set for the price! I find it very useful that both the compressor and parametric EQ can be bypassed if needed.
Ease of Use
Maybe I'm old-school, but I like having all my controls on front of the unit and I also like the option of assigning the analog VU to various monitoring duties. Easy to set up and use if you have any clue about audio gear.
For this price range, I was surprised. Nice solid pots and switches, solid metal construction, rack mountable, even comes with stick on rubber feet if you don't rack mount. Overall - excellent build quality.
Name one other unit which combines a tube pre-amp, two compression options, a four channel parametric EQ and then compare prices. Worth every dollar I paid, period.
The Wow Factor
I have to say that it looks sweet sitting in studio. People not in the know are easily impressed by all the pots, switches, leds and meters.
