Did a TB search but found nothing useful. Am in the process of fixing up an old Peavey 215 mostly for the fun of it, but do of course intend to end up with something playable. I have this idea of doing a custom grill design (think 50's US cars) in a mix of cloth and metal complete with chromed parts (as long as I can get it rattle free). My question is: how does grill design affect the sound? Is there some rule about max surface area? Holes versus slots? Saw an Ashdown cab in a shop recently with what I thought was an unusually "compact" metal grill, and my Eden 410XLT has a fairly large grill surface area as well compared to some other cabs. Not being an expert on this at all I guess it is only my gut feeling that tells me that grill design should have some effect on the sound. Seems to me that many "boutique" cabs either have cloth or a metal grill with little surface area. Any advice/input appreciated, I'd rather not spend hours building this thing just to find out I have to remove it whenever I want to play the cab.
