I'm just now using the 500 as an effects unit, of which I like the layout. I've set up another bank for effects only/4CM, with the FX loop just before where the disabled amp model is.
I think I've got the levels right (+5Db on loop send, master 60% up), but I'm getting a weird hum when I've got the 500 in the amp's loop, as opposed to no hum with either nothing or just regular stomp boxes.
I'm assuming this is due to the power supply, and if so, any ideas how to get rid of it? It's not really loud, but me having OCD, I need to eradicate it.
I'll Google it too, but I trust you guys much more than random assclowns on the internet.
Eh, looking around, it seems like the HD stuff doesn't play nice with Mesas in particular, and in general can be problematic in 4CM.
Balls. Buying another effects unit when I've already got this is a bit of a bummer. Perhaps I'll try it in the loop, no 4CM.
Trying it solely in the loop may help, but I don't know for certain. If you're only using it for modulation/delays, you wouldn't really need the 4CM.
