The MT’s are amazing in the SSH. They really nailed it with pairing them with NF. I’m sure the LT’s will be excellent as well but I wouldn’t want to change the MT’s in my SSH for anything. IMO the split sounds are the absolutely best humbucker split (or tapped) sounds ever, very convincing. To me, they are much better than the TCI pickups (Pauls guitar, MEV) when split/tapped. The TCI’s however sound great in humbucking mode.
I have both a Special Semi-Hollow and a Paul's Guitar with TCI pickups. In my experience the 58/15MTs in tapped mode sound very close to the TCI pickups in full humbucker mode. The TCI's when split sound very thin and anemic to me, whereas the 58/15MT's sound fantastic in tapped mode. Flipping the 58/15MT's to full humbucker mode takes a great sounding pickup and just drives the amp that much harder, more like a boost than a single coil vs humbucker difference.
