I got one of these pre's a few weeks ago and I would like to do a review of it. To star of with is this thing rocks. The sound is very clear!!! Not colored in any way. It has a Passive and Active inputs. A toggle for more Bright, Knobs for Gain, Treble, Mid, Bass, It also has a PARA MIDS with Frequency (250 Hz to 1 KHz) with a Mids gain. Also has a build in compressor with a on/off toggle. There is also the Sonic Maximizer with a LO Contour and a Process knob. And last is a Master out. With one DI out on the back. The thing Rocks. I like it very much.(only two gigs and one practice with it) It give much more volume without having to have it loud. Thanks to the compressor and Maximizer. Cuts through the mix of the rock band I'm in.(two guitars one drummer one singer and me) a lot of sounds can be take in out of this pre with some good fiddling of the knobs.
