I have an acoustic /electric guitar with Fishman IV electronics. I just purchased a Gens Benz Shenandoah Jr amp 35w. I'm getting minor string buzz and bass over tones that are annoying, no matter how I adjust the tone controls. I plugged in my Boss EQ pedal and solved the bass overtone and string buzz but have sacrificed clarity. It's now a bit of a muddy midrange tone by comparison. Not bad, but not good. Is there an inexpensive pedal or preamp designed specifically for acoustic guitar that would bring out more clarity to make the tone more true to life.
