Any other CXC owners out there? I have a cxc-400-1015. In small venues it works great. In larger venues I add a 4-10 cab and it changes formes to a really killer amp. But why don't I see more about them here? The resale on these amps are almost funny while the tube pre-amp WT's go for about 50% of new list. Oh yea my extension cab is an XST 410. Any information on these would be appreciated.
