If memory serves, Chris DeGarmo used Soldanos, where Michael Wilton changed his amps amps fairly frequently.
Marshall Silver Jubilee 25/55 100W Amp Head
Hughes & Kettner Switchblade 100 Head
DigiTech GNX2 (yep, a GNX)
Bogner Uberschall 120-Watt Tube Guitar Amp Head
Roland JC-120 Jazz Chorus
Vox AC30 Guitar Combo Amp
Hiwatt Custom 50W 2X12 Tube Guitar Combo Amp
Marshall JMP 2203 Mk II Master Lead 100w
I would start with the DeGarmo sound. Good luck!!!!
