Re: piezo pick hum

Piezo crystals have a very high output impedance, this makes then very susceptible to RF and other forms of electromagnetic interference. However, it looks like the Soloette has a built in preamp, so the output impedance will be much lower than the pickup itself, and shouldn't be a problem.

Do you hear these noises when the guitar is connected directly to

This does not happen with regular electric guitars. My technician says it
has to do with the piezo. When I put a finger on the jack cable that sits 
the connector in the guitar, the noise stops.
I can get rid of the deep hum with a plugin, but the high whining noise is
still there. I can't play with my finger on the jack cable all the time. Is
there a simple way to get rid of that noise?  a special VST plugin?  or 
kind of grounding cable that I connect to the plug? and where does the 
end go?  I need a quick and simple solution. Help!
