It seems very unlikely that the tub spigot is clogged, right?, so that

In case I wasn't clear, this is a separate diverter valve, btween the
hot and cold. Not a handle in the spigot that pulls up and makes the
water got to the shower.
Put in new guts for diverter valve. Fairly easy to do. Your local box store
should have the guts for it. My house was built in the 50's and has three valve
system and I can still get parts for things like this.
