I'm hoping one the the Laney aficionados here can help clue me in on the whole GH line. I see there's the GH-S, GH-TI, GH-L, GH-R plus the VH-R & Ironheart. I see they all have different slightly controls. My understanding on the VH-R is it's a 2 channel GH. And the Ironheart is like the spiritual successor to the GH line.
So are all of these the evolution of the line adding extra features, the -S & -TI are signature/Tony Iommi edition and they all sound the same? Or are they different amps that sound different, but lumped into a generic GH series?
