I like the tone of my 400+ through my NV215, but I want something more out of it. I recently bought an Ashdown ABM500, and tried that, and while it was good, it just wasn't what I was going for. I'm looking for something thats reliable, has a smooth distortion, and preferably is all tube. Like a vintage SVT, only without the constant maintanance. I think the AD200B is what I'm looking for, but where in or around New York City can I try one out? Also, along the same lines, and hints as to where I mght find one used? I've tried ebay, bassgear.com, and craigslist, and they didn't have anything. I'm not sure if I can afford a new AD200B right now. Thanks.
