I'm trying to figure something out and would love some input. I own a Marshall 9001 tube preamp going into a 8008 valvestate, and a line 6 valve 212 which I actually use most of the time. Loads of people claim that you need to use pedals in front of the amp for overdrive and distortion. However seeing I use tube amps I actually prefer the amps own breakup on certain presets instead of the pedals. The pedals somehow sound "artificial" I do have to add that I use a Marshall se100 which takes away app 12db so I'm playing at relatively higher volumes than in a livingroom setting. I have a distortion pedal that I don't like at all (bought it very cheap) and the ice9 from vox. The ice9 I do like in front of my chain for certain sounds but in all honesty I wouldn't buy it full price seeing what my amps give me. Would love to hear your opinions. I know tubescreamers were used to push amps with only a master volume or not so good dirty channel. But I'm doubting myself for the use on amps with really good lead and dirty channels. So looking for input.
