I am visiting South Korea next month (last two weeks of April 2017) and, although I'm mostly staying in Seoul, I wanted to visit Busan for 2-3 days by taking a KTX train. I'm considering buying a Korail pass, which is cheaper than directly reserving/buying a roundtrip ticket. However, as noted by the link,

Seat reservations will be available after redeeming your Pass at the ticket booths. Pass- holders, who fail to make reservations, may use unreserved seats.

I'm planning to visit Busan during the weekdays, most likely a Tuesday -> Thursday trip. I arrive in Seoul the Friday before this, and this would be the earliest time I could make seat reservations.

Do I have to worry at all about the trains being too full? Would it be worth it to just forego the savings and reserve a roundtrip ticket to guarantee a seat?

Usually, in my experience if you travel during the regular weekday and not on a weekend, during Seolal (Lunar New Year) or Chuseok (Harvest Moon Festival) there are several seats available between Seoul and Busan.

    FWIW: I ended up reserving a seat the night before each train ride, and I didn't have an issue. Thanks @FullMetalFist for your help!
