My rig, currently, is... Sunn Coliseum-300 Hartke 4.5 XL SWR Workingman's 12 Behringer V-amp Pro I have the left channel of the V-amp going thru the Sunn-Hartke combo and the right channel thru the SWR. I just bought this: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=10171&item=2551243568 My idea is to add this to my Sunn stack. The SWR is mostly a practice amp. I just using it as a right channel amp to check the effects. Anyone see any problem with my stack idea? I've never had a stack before (a-heh a-heh).
