This rackable distortion box is a great simulator of analog distortion.
It's basically a distortion box that can be used on anything from guitars, basses, drums and drum loops, pianos, vocals and almost anything else. I've heard that it is possible to get good sounds out of running entire tracks through it. It's maximum output level is +20dBV and it can range from .2 to 99.9% distortion
The setup is pretty easy. There are two channels (stereo) and each channel has an input and two outputs (lo and hi). There are knobs for drive, bias, and output for each channel. There is a switch for determining which distortion type you are looking for. There are also switches for overdrive and bypass, as well as the power switch. All switches are identical on both channels. A little more than I was expecting but easy enough to use.
This box is too versatile for its own good. The sounds you can get out of it are almost limitless. While you may hate some of the less distorted sounds on an electric guitar, it might work wonders on vocals. There is really something for everybody with this box. Sometimes the amps that you are using just can't do the trick, or you are doing something and it's too clean and polished sounding. This box is perfect for that. I mainly use it on guitars but I've also had great success with vocalists who are looking for a rough, raw sound (punk and hardcore bands).
I like the versatility and warmth that can come out of it. I like the fact that it also can really rip when it's cranked. The price is definitely up there, but worth it if you are recording the kind of music that needs a little (or a lot of) distortion every now and then. Its worth the buy.
