Agree, you have to nail 'em...and not just you nailing (or best humanly-possible approximation of, best most of us can hope) the guitar parts, the WHOLE band...if you try 'em and they don't work, throw in the towel pick another one....ever tried 'Unchained' and actually tried to get the Flanger-Chugs
correctly timed rhythmically? Not easy! For "Romeo Delight" you
have to do the low E string tap-by-the pickup trick after the solo during the "Feel my heartbeat" bit coming back in to the chorus...."D.O.A." also way fun to play live, but possibly tougher on the singer than the guitarist, getting the DLR-howls right.
I've worked with singers over the years that probably had better technical ranges that said Dave is "unique" and hard to nail.
IMO doing VH tunes or anything that cool as a guitarist is a two-part undertaking: Getting the licks right, and
then getting the tones as close as possible. I'm glad I picked up the MXR EVH Phase90, the 'script' mode gets pretty close to the classic chewy solo sound, and I have an MXR Flanger model programmed as a preset on my pedalboard's MM-4...I was annoyed with the fact that my last band
only wanted to do the "safe" ATBL YRGM stuff. While I was still happy to be playing CVH tunes, I'd rather have been playing some of the (non-'standard') cooler tunes... too bad I didn't have as involved a pedalboard in the earlier band, would have been better utilized then.
Having said that, I'd still rather be playing any CVH tune over some of the bland 80s-90s-contemporary shit some cover bands in LA want you to play...ugh. But another interesting bit about playing the heavier stuff in bars: The owners/management loved that they did well over the bar with us, but on more than one occasion said we got the crowd, and I quote "too rowdy" - like Van Halen tunes
aren't supposed to put people in a festive mood...?
But yeah CVH tunes and Rhoads-era Ozzy you don't really put a "spin" on...you PLAY THAT SHIT.
