So the answer is when the guitarist can play odd times but the drummer can’t?
Sounds like a song choice/ genre/counting practice thing...especially if the guitarist has been playing odd times as a favorite music choice for a long time and the drummer hasn’t.
But can the guitarist suggest...
Curious....🤔When is a guitarist better than the drummer? Is it a speed thing, song choice thing, time keeping thing, what? If you can cover Hendrix’ , Page’s, or Clapton’s songs are you,as a drummer, their “equal?”🤔
You have to get rid of that left hand wobble first, so use your wrist and not your fingers. And do left singles ‘til the strokes are straight down and comfortable.
Then use your fulcrum fingers doing the same thing, bouncing the stick. Your hand will eventually grab the stick on the rebound...
You need a stereo output of more than 50 w / speaker, speakers at ear height behind you each side, wear earmuff-type protection and you’re good to go. Drums alone should sound “gated” then you know protection works.
