I know the Bogner XTC is a very well respected amp and the price to quality ratio on the 5150 is incredible. I play a 7 strings and mostly play chug style chunky rhythmic stuff. Which amp do you all think would be better? BTW I have a Bogner Uberkab and I've tried a 5150 1 through it and was amazed at the silky smooth gain this thing had compared to my rectifier. The low and was tight and there was no struggling to get a good smooth heavy sound. How does the XTC compare?? I may have an opportunity to get a good one used but I havent played it yet. Thanks!
