Your safest bet is to run 4 conductor wire and outlets. All new ranges and
dryer circuits must be 4 wire. As far as I am concerned, all new amplifier
circuits should be too.

Many amps like an Ameritron AL-1500 have a 3 prong plug. 2 hots and a
ground. It does not require a neutral so you only need a 3 prong plug. Any
appliance that requires 120/240 volts will require a 4 prong plug as you say.
But
not all amps require 4 prongs. However it is good to have the extra wire in
the box if you come across an amp that does need the neutral.
