I have a Genz Benz combo that I use for practice, and I have a cheap no-name cabinet that I use with the combo when we play live. I want to make the two match better. I'm going to take the logos off the grill, and I already painted the wood that the speakers mount to on the combo black (it was gray). So where is the best place to get grille for the front of cabinets? I want metal grille material...no cloth.
