Re: Preferred or Best Acoustic Amp?
I prefer to plug my acoustic guitars into my Peavey XR-600 top box and a speaker, typically a PV 112HS floor monitor. That gives me the most flexible patching, reverb, 3-band EQ, and a 9-band GEQ for feedback control if I need it. Set up is easy; and you have the advantage--over a combo unit--of placing the speaker to minimize feedback while keeping the controls handy. Also you can choose which speaker you like best for your guitar. And in today's market you can buy these pretty darn cheap!
The other one I use is a Guitar Center-made Acoustic Control AB-50. Two input channels, one set of tone controls, no effects. Ten-inch speaker and piezo horn, 50 watts, and a ported slant cab--designed for acoustic bass, but these work very well for acoustic guitar, bass and drum machines. Also cheap!
And another good way to go is with one of the many plastic, powered PA speakers on the market: Thump, Mackie, JBL EON, Peavey, Yamaha, Carvin, Alto, Behringer--all make 12" and 15" biamped woofer/horn PA speakers varying from 150 to 400 watts. Most of them have built-in mixers and can be stand mounted or used as floor monitors. Need more inputs? Add a small PV, Yamaha, Behrenger, et. al., mixer.
I have the Aura DI, which is very handy for open mics when I want to take my Taylor 710 CE with the Fishman Stereo Prefix blend, or my Martin D-28 with a Fishman Ellipse Blend pickup. I'm using my Martin DC Aura these days over the Taylor (which may be going bye-bye), and finding that it is much easier to get a great sound out of the Aura system. And the DC Aura is a great sounding guitar!
