Re: Picking up a new instrument?
Playing a more rhythm based instrument will never hinder your drum playing!
..unless you never drummed again!
Most guitarist that I know who have playing some drums in the past are often better(I find) than those that don't..teaches them to move the percussive aspects while formulating a melody.
Anything to do with music, albeit mandolin, recorder, stomping your feet..its all your 'training' so to speak.
Cheat away, I say.
