I need some help guys. I've got the money to get a new amp and I can get Yorkville stuff cheaper than anything else so it's a choice between the YBA200 head and matching cab or the xs400t combo with an extension cab (either 2x10 or 1x15). What about the xs400 head with a Yorkville 4x10 cab? What are the differences in tone? Which is louder? Any problems people have found with either? Just any help with decideing would be great. I know I already made a similar thread a while back but that was asking for sound files.
