Line6 and Bogner

[FELINEGUITARS]

I'd say that pretty much nails it. Or if you want you get the Pod and the Atomic 16 combo in one piece of equipment - more or less ... but with a Bogner logo on it  

I quite like the Atomic 16 (would love to try the 50W version)

Much better with the Vox tonelab rather than the POD (IMO!)

From what they're saying in the videos on the Line6 website, it's a full Spider preamp run into a typical valve output stage.  

The Line 6 modeler feeds a pair of 12AX7 preamp tubes.  The first tube is set up as a cascading gain stage, with each stage contributing the harmonic complexity vintage amp players love.  That feeds the master volume which hits the next 12AX7 configured as a phase splitter which is followed by Sovtek 5881WXT/6L6. There’s 2 6L6’s for 40 watts of class AB power in the combos and 4 6L6’s for 100 watts of class AB power in the head.

This is from the line 6 website.  http://uk.line6.com/spidervalve/bogner.html
