if your guitar is bassy and dense sounding like my '73 les paul custom, I highly recommend the riff raff/mule combo, and a booster for the metal and 80's hard rock stuff
I had a lot of bkps in this guitar before setting on these
I tried nailbombs, cold sweats, black dog, holy diver, aftermath and a motor city set
if your main concerns is high gain only, most of the contemporary line should work well, but the riff raff works just as fine
the riff raff shouldn't be hotter than the t-top, but it's punchier and waaaay clearer under gain
it does Tool amazingly well and handles the Hetfield picking really well for an alnico pickup
but I bet a rebell yell would sound great in this guitar too
