I had an SP77 just like that! And a G Major, and a palmer...hey you've got my old rig!
It'll sound great, try running the 9005 in stereo, but have one side wet and the other dry - you loose stereo delays but gain clarity. If you can pick up another power amp, then run three cabs, stereo wet FX, and a dry. I did this for a while, but then some moron ran my car of eh motorway and I wrecked my back so gone are the days of huge rigs without a roadie!!!
