Piezo Question

[ericmeyer4]

I have a few piezo questions... I am trying to pickout an acoustic guitar and knowning a little more about piezos I think will help me.

I understand the basic idea. (ie string pressure/vibration is pickup and then it is amplified)

Say I have a piezo and I place it in guitar A and the same piezo I also place in guitar B. Just to narrow the variables the only difference between acoustic guitar A and acoustic guitar B is the type of wood used in making them. Lets make A have a spruce top and a rosewood back and lets make B an all mahogany guitar. Acoustically these guitars should sound different. Here is my question if I were to plug them in would they sound different in the P.A. system? Would they sound like individuals or would they just sound like a generic acoustic guitar? BI know with electric pups if its the same pup in two different wood types there would be a sound difference between the 2 guitars. I wasn't sure if piezos worked the same way.

Thanks for the help,
edm

Re: Piezo Question

piezos do 'neautralize' accoustic sounds quite a bit as for the most part it doesn't pickup and of the body cavity resonance directly. But wood definately has an impact because it effects the resonate frequencies. the body size has impact from this POV, as well.

Compare a concert sized piezo against a dreadnaught and you will notice the difference

Re: Piezo Question

hmmm .... i dunno the answer for true acoustics with a piezo bridge ... to me, with solidbody electrics, i heard very little difference with the same piezo bridge in different models ... i gotta believe that the total composite sound would be different because of the acoustic properties component ... but given that you would ideally be processing the piezo ouput (heavily) in order to get good dynamic and EQ properties, i'd bet that it really wont matter too much

try the DTAR forum for real acoustic knowledgable folks

good luck
