For what its worth this was my rig many many years ago
a really old GP11 series 2 with the original hard wood case UV light and giant fan plus a series 6 200 watt head(not pictured)
a 1018 1x18 cab which sounded great and a multi stack 2x10 on the top which I used to give to our drummer on gigs
the GP11 used to break down a lot so I replaced it with a Peavey Firebass 700 which turned the rig into a monster
sorry bout picture quality its a scan of a photo
