I’ve been playing around with amps, reverb, delay and echo on my Native American Flutes. The results are amazing. They make me sound like I am in THE PERFECT CANYON and almost know what I’m doing! So if anyone out there is thinking about the “Mini -FX” (The Oregon Flute Store) or “Microcube” (Laughing Crow Flutes) systems — just buy them both. Cry once when you spend the money but you won’t be sorry after you listen to the results.
