I'll do some:
Clean: Hated it. Dull. All I can say about that one.
Blackface: Love it. Very robust, clean, bright, all the things I like in a clean module. Could use a little more mids, but other that, exceptional.
Plexi: Loved this one. Nice crunch, and with volume and good technique, you can actually shred with it. Could have used a bit more warmth and clarity. COUGH COUGH Pete.
Recto: Good. Wish I would have kept it and did the grail mods, and a little of my own to it. Pretty sure I could have made that thing a beast.
XTC: Perfect for smooth, thick leads. Does as advertised, sings like a bird. Not a good rhythm module if you do fast metal stuff, but with a cap change, it does really well. Pete's new and old mods on this sounded great. Actually preferred the old mod with this one.
SL+: JCM 800 specs. Enough said.
Ultra: Good, but lacking mids. Very sizzly. With some added mids and some hint of this and less of that. I actually think this could come close to an SLO. This is likely to be a modders money maker if they start modding one of the modules to this COUGH COUGH PETE.
Ultra XL: My favorite metal module. Shredders dream. Would be great to add some thick mids with this one as well. No complaints for this one. I love it.
Now that I am posting this, I am going back and forth of whether I should sell my rig or not. ENGL Invader is coming from the MAILMAN, and I have a feeling that one bad *** amp won't be enough. Monogamy is so hard when it comes to amps and guitars. :wink:
