Re: Pickup advice please
From my shopping on this, I would point at two possible solutions:
Schertler. Use the putty to put it on the soundboard when needed, clean it after. Expensive, but said to have fairly natural sound.
Clip on mic. Seems like there's quite a number of happy users of the clip-ons who like the natural sound from a mic.
I have a K+K piezo system, I like it ... I think that a discerning ear in a good listening environment will be able to hear a bit of piezo in the signal. It's not bad ... just fine at loud volumes [natural enough], but I can hear it. I don't think the Radius would be a bad solution ... but if you're looking for the most natural sound, not my top choice.
