VV: Points taken and agreed....mostly ? I understand the point of you comment and accept it 100%.
As for the Spider Valve....well, I don't quite agree. I'm not trying to be deliberately overly academic (I do agree that many replies on GFSA, including many of my posts in retrospect, are just that) or to be obtuse or to confuse lesser experienced GFSA members. I'm just interested in the truth of the matter. Should anyone search "Spider Valve" in future and read under this topic and get incorrect information, we wouldn't be doing our part as experienced GFSA members, would we?

I think the description of the Spider Valve being pasically a "POD 2 in front of a valve power section" is far more inaccurate, since the Spider Valve has preamp valves too ?
It uses POD 2.0 Technology according to Line 6, and is basically a POD 2 in front of a valve power amp, or, for the sake of accuracy: a cut-down POD 2.0 in front of a clean all-valve amp. Yes it, has preamp valves in addition to the output valves, but they are not heavily involved in the tone generation besides creating a good clean base for the POD digital amp modelling to produce the tone.
Here's a quote from Guitar Player Mag's review which helps explain it:"Your guitar signal first hits an analog-to-digital converter, a DSP, and then a digital-to-analog converter. So it’s not a tube front-end per se—rather, the two 12AX7’s prepare your guitar’s signal for the dual 5881 output stage..."
What are the significance of the preamp valves and do they add as much to the tone as the output valves? That is debatable, but most would venture that the output valves do more to make the tone "valve-amp like" than the preamp valves. But really, that can be a long and complicated debate that we probably shouldn't get into.
I'm sure you understand all of this already - like I said, this is for the benefit of the uninformed.
As for the Line 6 Spider Valve itself, I think it's a very good amp, considering the price and features and while I wouldn't buy one I can see - and hear - why it's a popular amp that appeals to so many people. I have no problem recommending it!
