Dave, Terry,
There were a number of factors that contributed to the lack of "That Sound" at the Reunited tour (and most others). Here the benchmark is the Kingston concert live sound as it is very difficult to reproduce the Abbey Road recorded sound live without a lot of fiddling, not really a proposition for a major concert tour.
Firstly, the sound heard was mainly through the PA system and not the same as straight from the amps (I know as I heard the raw sound in the rehearsal studio in Perth and it had much more "growl", more like the Kingston sound). Secondly, he doesn't adjust the amps for any different sounds for different tunes. Thirdly, he now mainly uses the bridge pickup on stage whereas many of the originals used middle or neck. But probably most importantly, Hank's playing style has changed considerably over the years. I did a video on this latter aspect some time ago using Apache as the example:https://www.youtube.com/watch?v=mXp9gMU0pLc&feature=youtu.be . Players like Colin actually play more like the old Hank than Hank now does, and that has a major impact on the sound.
Finally, with regard to cost, most TVS3 owners seem to think that the cost is fully justified, as evidenced from their unsolicited testimonials available on the TVS web site: http://www.tvsspecialtyproducts.com/testimonials.html .Dave might be interested to have a look at what he wrote back in 2008.
Paul.
