In my Santa Cruz i use a Highlander microphone into the Baggs Para-Acoustic DI, Zoom 507 reverb in effects loop, then into a GK250ML guitar amp. The amp has 4 band eq, with two 50 watt power amps, built in chorus and echo, all pumping through two 6 inch speakers. I can run p.a. cabinets with this puppy. It works for both small and large rooms. The Highlander has some high end "sparkle" that is a bit troublesome, but I get a sound much nicer than any piezo I have heard. With the large band, it's Sennheiser mics through the Mackie board and then to the big cabinets. After a dozen gigs we finally got it right. An audience member who is a player said, "Sounded like Tony Rice."
