Just wanted to share my experience. I went to GC in Nashville Tn. They had 2 Bogners and the VHT Sig X. I got to sit in the amp room and jam on all three models. I was able to crank them up and let them go. I have read a lot of reviews on here about all of these models so they have been on my hit list for awhile. For me the VHT had nothing to offer. I tried to dial in several settings and just could not get a sound that I liked. The lead settings had some cool features but it just did not work for me. Next up was the XTC. I was excited to finally test this model. It was by far the best amp that I tried that day. A fews guys came by and stated that it had a killer sound. Oh I was using an Ernie Ball guitar. Nice guitar as well. In the end the Bogner was still a little loose for me and I did not get what I needed out of it. Great amp but not the Be All End All that I thought it would be for me. I switched it around to several different 4X12 cabinets as well. For me it was best out of a Diezel cabinet. I know that for many this amp is the One and I can see how that could be. I like a compressed, tight sound and I was not able to dial that in. The Shiva had some great tones as well but again for me it had the same short comings. All 3 Amps are class amps and I am sure for many they are a perfect fit. At the end of the day it was nice to go home and realize that I have what I need. I dont know why some of us cannot be happy with our rigs. Then again it is alot of fun to try out new gear. You never know when you will come across something that really makes a difference.
