Floyd rose bridges - Pain in the a** to tune.
zoom pedals - matining/ngongo/mejo mahirap itweak for me.
fuzz pedals - di ko trip yung tunog
maybe some other time
dunlop 9s - parang ang tigas/kapal pa rin for me, ok din naman tumunog, madalas kasi gamit ko d'addario super light
bass/guitars na may matabang neck - sakit sa kamay, though yung fernando musicman copy ko medyo mataba nga yung neck, I'm getting used to it.
Lava cables - too pricey and ikaw pa mismo magaassemble, looks fun, but to think of the errors, ang mahal mahal nun.
just my opinion.
