So I'm about to purchase some tolex to cover the cab I'm building. It's a 4x12 that's 42" tall x 25" wide x 18" deep. How much should I probably get? And how in God's name do you cover all of it and make it look smooth? All professional cabs make it look so smooth around all the corners and it seems to be one continuous piece. Also... I'm trying to decided what color to go with. I have both and Orange AD200 and an Ampeg VR.... and figure that black would go with pretty much any amp well. BUT! I want my cab to look unique and different. Any suggestions? Anyone know of some sort of black or cool tolex that has designs made into it? Thanks.
