Narrative:

Aircraft X was handed off from north radar to me over mavis outer marker at 6000 feet heading 160 requesting a par approach into svn. Svn was on runway 10. I descended aircraft X to 2500 feet. A VFR aircraft was assigned at or below 1500 feet just south of aircraft X; heading northbound. I vectored aircraft X through the svn runway 10 final approach course and assigned a right turn heading 010 and descent to 2000 feet for a right base leg. I coordinated with svn ground controlled approach (gca) that aircraft X was on a heading of 010 descending to 2000 feet. I then switched aircraft X 'contact svn gca on 137.4.' aircraft X acknowledged. During this time; a VFR pop-up called reporting 30 miles south of atlanta. I assigned a squawk code and asked it to report his position again. I allowed myself to become distracted with the VFR pop-up and his request before I realized I assigned aircraft X the wrong frequency. Aircraft X returned to my frequency to confirm the gca frequency. I then assigned him the correct one; 134.7. By this time aircraft X had penetrated the 2500 foot minimum vectoring altitude 9 (MVA) north of the final approach course. Svn gca established communications and turned him southbound out of the MVA area. I should have maintained positive control of aircraft X and kept him at 2500 feet to protect for the MVA. I should have confirmed the gca frequency by referencing the quick reference display located just above my position. I should not have allowed [the other aircraft] to distract me with his request. Lastly; I should have asked for a handoff earlier. My recommendations to prevent the re-occurrence of this event is to maintain positive control and to double check frequencies. Slow things down and make sure to pay more attention to higher priority traffic and not get distracted by things that could stand by.

Title: SAV TRACON Controller issued an incorrect frequency to an aircraft. The aircraft became NORDO and proceeded into an area below the Minimum Vectoring Altitude.
