New York amp show- Celestion booth.  I was trying out the original Overdrive Special they had with some 12-65 speakers.  Premier Guitar film crew walks in and asks me if I want to demo the amps in the room- the Dumble, a Trainwreck Express and Liverpool, and some Brunos through different (some unreleased) Celestion speakers.   An offer I could not refuse.
The video should be up on the Premier Guitar site soon.
When I was done, I went straight to the Bludotone and Fuchs booths while the sound of the gods was still fresh in my ears.   All very nice amps, each with a slightly different flavor. Killer Steel String Singer clone in the Bludo booth.   Nik....please clone us one of those too.
When I got home, plugged into my S and M.  I still love the damn thing...every bit as valid a voice as anything I played today. 
Also tried a an EV Theile box and 12-65 oval backed cabs.  My Two Rock 12-65 1 12 still my favorite compromise between clean and dirty.
Yes, boys and girls, it was a good day.

The following are my impressions of the amps @ the NY show.  Please keep in mind, all were played in very small hotel rooms, and might sound totally different in alternative situations.
Dumble:  Great OD at low volumes, cleans OK, but not spectacular,  gave up harmonics in OD easily, more subtle change in PAB and boost modes than the S and M, Deep boost was deeper than deep boost on CT,
Seemed to like the 335 the guy before me was playing much more than the Tele.  If anything, the S and M sounded a bit more like the David Lindley clip on youtube and the Dumble like the Hilden 335 clip.
Theile ev cab.-  sounded small to me, especially next to the 2 12 semi open backed ones.  Maybe they really need to be cranked to get singing.  I thought it would be much fuller than my Boogie Mark combos, but basically the same flavor, albeit with a bigger bottom
Bludo 80s dumble clone.- a bit harsh before he added the Bludodrive- Bludo drive had more pronounced smoothing effect than the Klein.
Bludo S S S- Physically very big head, more than I'd ever carry.  Beautiful, thick cleans, -not Fendery
Fuchs HRM-  Cleans very similar to the S and M, very gainy overdrive, a bit thinner than the others- reminded me a bit of my late Boogie mk 4.
Trainwrecks- loud, aggressive, full sounding.  I really didn't have any prior experience with that type of amp, so I don't have anything to reference.   I did really like them. 
 It was more - "just start playing something and we'll start filming." 
Of course, my playing was sloppy as hell, ...oh well.

I did try it, but I don't know if it was filmed by PG.  Not quite as special or memorable.
