So I finally got an Ampeg 810, it's old enough that it doesn't have wheels or a "handlebar," it's just a rectangular cab. Here are my questions: 1. On the bottom are six 1" diameter holes that used to have metal cups in them, which I understand fit the dolly that these cabs originally came with. The owner I bought it from had installed casters over the four holes on the corners. The casters were shot so I took them off, leaving 4 screw holes around each 1" hole. I haven't been able to find casters with the same mounting screw pattern, and I've been using it for about 18 mo. w/o wheels, really not too a big problem, using a hand truck. Option 1-Parts Express has a detachable caster with a flush mounting plate that the wheel assembly slides into, ie no large deep holes like pop-out casters require. Assuming the screw pattern doesn't match, would 4 additional screws in each corner cause any problems? I'd still use the handtruck for major moves, like to & from my truck. Option 2- Something similar to the original dolly. I haven't yet found an illustration of these, and have no idea how efficient they were. Option 3- just use the damn handtruck. Other options? 2. The tolex has various rips, gouges, and patches where it's gone. I don't want to mess w/ mojo, I don't mind some roughness, and I'm not interested in recovering. I plan to glue down any spots I can. Any pointers on how to do this, what kind of glue, etc? Some spots I'll be gluing tolex to wood, some places tolex to tolex. What about bare spots: let the bare wood show, patch the tolex, color the wood black, or something else. 3 I'm definitely going to get a heavy duty cover to prevent some of this from happening. Is Tuki the best? Other ideas? Thanks for any experience or creative ideas anybody has!
