Ok, I was trying out some new gear,and stumbled upon the new GK1001RB II . Played it through a 410 GK cab ,,( I have finally found the ultimate tone for myself). I had the salesperson hook up a 410HLF with the GK head . The salesperson fiddled around with the speakon cable while the head was on ..Poof !! , Big puff of smoke came out of the fan , and that was it for the fan ,the head kept running ,and kicked major but. I had the volume under three,and this head just wanted to shake the walls down. Now for the discontinued GK 1001RB ," Can I expect the same ass kickin power from this head also ?
