Now I’ve got a tumnus deluxe for cleaner sounds, a euphoria for light overdrive, a plexi drive deluxe for crunch and boosted leads, and this bad boy when i want to bring the house down

(I think the double switch is more useful in the new Plexi Drive Deluxe, where the "Boost" switch is actually a standalone tubescreamer that can be engaged even with the rest of the pedal in bypass).I won't spend too much time trying to describe the sound of the Pinnacle - if you're familiar with Van Halen's tone from different eras, there's a good chance you find that somewhere in the Pinnacle.
