UTILIZATION

It's got the same amount of knobs a regular combo or amp head would have, so if you have experience with regular amps you'd be very familiar with this one as well. Rack stuff is a bit more complex most of the time as there's more connections, ins and outs to work and most of the time they're all in stereo configurations. I personally was never into the rack stuff, owning the vooodoo labs preamp was an experiment of possibly getting into it for me.






SOUNDS

Ok the sounds but first, for anything modern like modern metal or whatnot, this is not the preamp for such a thing. There is enough gain on tap to accomplish metal tunes but the sound of the preamp is very thick and also has a very prominent mid range. So this amp isn't really meant to get super high gain, scooped death metal tones.

Ok now that we got that out of the way. As far as I remember, the sounds were quite good for bluesy/vintage/classic rock stuff. It's generally, a very smooth sounding preamp. Leads are nice, warm thick and lush. Rhythms are fat and thick as well, CAN get a bit muddy depending on how you set it, again this amp's midrange is very big and almost exaggerated so you kind of have to take that into account. The cleans are very clean, lots of headroom and plenty clean. They aren't super bright and twangy like a fender but they are still very good. The bright switch helps to get CLOSE to that ballpark but not exactly, more like just adds a bit of sparkle to the top end.

OVERALL OPINION

Overall it's a very good sounding preamp for classic rock and good cleans. It's got a warm vintage sound with plenty of midrange. It also is a bit dependent on what poweramp you use but overall this preamp is geared towards a smoother sounding overdrive/distortion. Definitely not for the metalheads. But if you want nice tube analog distortion and wanna try something different from everything that's out there today and like simplicity in a rack, this is a good one to look into!
