With my GK setup, I have liked the Superfuzz [with a Boss LS-2 to give a clean blend], and have used muffs too. Not super excitied about RAT type pedals with the GK. Also since the GK can do fairly mean on its own, a good overdrive sounds great. Yes, that means I am plugging the Way Huge Pork Loin again. Still my favorite pedal.I’m honestly pretty open. Since changing up my head and cab, I’m pretty much starting fresh again with tones. I went from Aguilar AG700 with a GS212 to a GK 400RBiii and a GK212 neo. I still have my Darkglass B7 Ultra, but it’s got a pretty specific use anymore. It doesn’t really factor in to my normal setup. A muff style fuzz would be pretty awesome I think, but I’d be more open to suggestion than set on any one fuzz.
No good for that kind of stuff, great if you want a HUGE and rich sound, I tried some O))) stuff with the Kramer and a Cloven Hoof and it went on droning forever without even touching it
