So I'm accidentally short one TL072. Could I use a TL082?
Technically, yes. They can be used in place of eachother.
The datasheet schems are the same.
However, I don't know the impact of sound the 82 will have instead of the 72.
Texas Instruments says that "The TL07x series are the low-noise versions of the TL08x series amplifiers."

Cool. Ill just socket the IC and swap it for the correct one later on. Thanks!
