I’ve been looking around for an answer to this and I haven’t gotten one I’m satisfied with. On a thread on here talking about all the guys vocal ranges someone said they were all tenors but didn’t specially say Felder. I have a hard time believing Felder was a tenor. He always sang the low notes on harmonies and he sings really low on SBR. Visions is also on the Lower side. He does do some of the high notes on OOTN and WW solo though. It could be auto tune however. Does anyone know?
