I'm not sure about the head but the 100DFX is a nice amp with a bitchin tone. I used one recently in the studio for the first time ever, always went DI before with my Mesa gear. To tell you the truth, next time I'll go back to Mesa for rhythm (it has so much more balls) but use the 100DFX for lead. Being solid state it has an incredibly tight feel which is really noticeable on high speed solos. I find that tube gear has a negative impact on realy fast palm muted runs because of the 'sag effect'. One thing about this amp is that you will only hit the sweet spot when it is cranked to at least 75%... and that is very loud... not ideal for playing at home.
