(In-struh-ven-shun N.) When a rock band holds an intervention as a group for another member who is consistently using an instrument on stage that is embarassing to the rest of the group.

This might include but is not limited to the use of a 6 string bass guitar, a drumset with two bass drums, a keytar, a double neck guitar, anything made by PRS, a huge marshall stack, etc.
Jeb: Dude, we gotta do something about Ron, this is the third gig in two weeks that he has whipped out his skin flute for a random solo.

Clarence: You are right, get the guys and a 12 pack together. We need an instruvention... and we need it now.
