I use a Bogner Shiva  with El 84 tubes.  As for the missing "ner," I woke up the morning after my 21st birthday and it was broken.  What I love about this amp it's simplicity.  It does exactly what I need it to do.  Most "boutique" amplifiers are laden with (arguably) superfluous features and switches.  The Shiva has a bright clean sound, a very usable lead channel (which I use with overdrive pedals), as well as, a surprisingly lush reverb.

 

While recording Only Human, we ran the head through a Furman Power Factor Pro.  The nuances of ones touch are more apparent when using the power conditioner.  In addition to adding appreciably more sustain, the Furman unit eliminates excessive noise.

In the studio we have been using a Mesa Boogie Rectifier 2x12 cabinet with Celestion vintage 30's.  The microphone configuration is an Audex (close) and an Neuman (ambient).

 

I also own a Bogner Duende 15w.  I use this combo for practicing and smaller venues.
