Hughes N Kettner Tubeman MKII
The Tubeman is a Tube Guitar Pre amp and is meant to be plugged it straight into the Soundcard. Its useful for people who have home studios and cant really Mic an amp. I absolutely love the sound of it and am using it to record all my guitar parts for the 2nd Album. I have used it live as well where I wasn't happy with the Guitar amps that were provided. You can also get some variation in sound by placing Overdrive pedals before the Tubeman.
MI Audio Crunchbox
This small little red Box remains my favorite Distortion pedal till date and I use it extensively for all my gigs. All the distortion comes from this going straight into the front of the amp in the clean channel. Even at high Gain settings the bottom end remains tight.
