noticed JK uses a lot of the same guitar effects on all of the band's songs, and I was wondering if anyone knew what they
were that gives him the sound he has. Thanks!

Here is an interview with him discussing his rig both guitars and effects. His guitars have changed and I saw somewhere else that he currently has an Alembic guitar on loan for this tour while they are making a custom one for him.
