Has anyone had any experience with this system? On AT's website, it's listed as a guitar wireless, but is it versital enough for bass? It looks like I could get it cheap on eBay, so this could be a possibility. What I'm looking for is a wireless unit that won't color my sound more than is absolutely necessary, plus has decent range. I wouldn't be traveling more than 50' or so from it, so I don't need that much range, but I'd like to have flexibility to go farther if necessary. It would be a big bonus if it was able to be converted into a rackmounted unit, when I move into the rack setup. TIA!
