"Though they were able to reduce an entire planet to a pre-technological state, even destroying enemy shields with one blast, these weapons were used only in relatively small numbers during the Galactic Civil War."

Source check? If the Empire had EMP's capable of destroying enemy planetary sheilds with one blast why did they build the Torpedo sphere, The Death Star etc? Why not use a combo of EMP and ISD to destroy all opposition :P
