Sonomatic: J112 vs J113

Hey guys, I am in the process of sourcing parts for the Sonomatic. It calls for J112 and I have some J113 that I was wondering if I could sub for?

Honestly I am not entirely sure what the JFET does (it's not part of a gain stage) and I am having a hard time understanding the switching in the schematic right now (long day!). I can post the schematic if you want to take a look, or if you just know the answer, I'll appreciate the help!
