Can the DA5 be mic'd up to a PA with good results? Here's the deal. I already have several amps including a Vox Valvetronix AD50, which I love - great jazz tone. But I want a small, versatile portable amp that I can keep in my car trunk (that's the "boot" for you Brits:) and use it for impromptu open mics and jams. Has anyone done this before? Also, can the DA5 provide decent vocals through the mic input? I tried the DA5 at GC and was impressed with it's clean tones. Your answers to my questions can help me decide whether I buy it. I want to buy it, but I need a good reason to purchase another amp.
