I just did my first Wavemap with my new Tonedexter on my Robinson 12 fret dread. I'm consistent with others above, the difference between the Waveform and the pickup is astounding. The difference between the mic and the Waveform to my ears seemed to be just a slight loss of volume but no loss in tonal accuracy. The pickup sounds muted in comparison. The guitar has a K&K and the mic I used was Shure KSM137.
