One of the ironies of playing harmonica through a microphone is that it seems that the microphones with the hottest, greasiest tone can’t be fully utilized because of howling, screeching feedback.
Under normal playing conditions, the Harmonicaster will not feedback unless you want it too even at maximum gain and volume levels!
To get the Harmonicaster to feedback you’d typically have to put the amp on overdrive, turn gain and level up pretty high, put the Harmonicaster’s own volume control all the way up, and then stick your face in the grille of the amplifier when you are playing. In normal playing conditions, whether you are standing in front of or behind your amp, the Harmonicaster will not feedback.
The Harmonicaster is a new thing and we’re still only scratching the surface of its potential. We’re going to explore the possibilities of controled feedback, so if you have aspirations of being to the harmonica what Jimi Hendrix was to the guitar, that just might be possible.
