In the recording side of his studio, Vai has a wall of various acoustic instruments that can be called upon if that specific flavor is needed. His console is a custom 500 series customizable console by Tree Audio. It has two rows of 500-series modules with compressors, limiters, and EQs that can be swapped out, as well as a section sized for conventional Neve modules. He situated the EQ so that he doesn't have to move out of the best listening window to adjust it. He uses Ocean Way monitors.
