A FREE download! Greg Heumann, a master harp mic builder, has distilled his wisdom into a 19-page document. The table of contents includes items such as "acoustic vs. amplified," "acoustic tone," "where does 'amplified tone' come from?," "tubes vs. transistors," and "dynamic and crystal [elements]: what's the difference?"

Modern Blues Harmonica is delighted that Greg has decided to share all this information with the harmonica community, free of charge.
