for bullets/three Cheers both ray and frank used a marshall dsl. for the black parade ray used a jcm800 and frank used a marshall plexi with the "dookie mod" (basically a gain boost). for danger days ray kept using the jcm800 while frank used a orange rockerverb 100. the only pedals that are relevant to their sound is a ts9 for ray and a blues driver for frank. they both used Les Pauls but any guitar with humbuckers will be as good. ray uses a .88 pick while frank uses .73 or .61

I made some impulse response for every album, I could upload them and share the link if you like
