The Studio Channel Tube Channel Strip by Presonus is by far the best bang for your buck, I own two and I use them on just about everything. They are extremely versatile. I have been recording music for eight plus years, I record everything from Hip-op to Heavy Metal and I have found that the "Tube-Drive" knob is a lifesaver. It allows you to add more dirt and saturation, as well as harmonic content right at your finger tips. It is truly amazing how dynamic this thing is, no mater what sound you're looking for, it can be made with this pre-amp. Whenever I am doing guitars direct in, I use this. It allows me to get a real tube amp feel without having an amp. All I have to do is crank the tube drive. I would recommend the studio channel to any recording engineer; it is a professional peace of equipment that is at a more than fair price.
